Kai: The Life Story Behind EXO's Dancer

The first thing you notice about Kai is not his singing. It is the way he stands. Even standing still, he looks like a dancer: straight-backed, balanced, aware of every part of his body, as if the floor beneath him were a stage. Then the music starts, and he moves, and the room changes. His dancing is not like other pop dancing. It is bigger, slower, more deliberate, with the control of a ballet dancer and the fire of a street dancer, mixed together into something that belongs only to him. Fans call him the centre of EXO, and they are right. When Kai dances, the whole group seems to move around him.

Kim Jong-in was born in Suncheon, a quiet city on Korea’s southern coast, on 14 January 1994. He was the youngest of three children, with two older sisters, and he grew up in a home where he was loved, teased, and encouraged in equal measure. His father worked in business, his mother looked after the home, and the family lived a comfortable, ordinary life. Nothing about it suggested that the youngest child would one day become one of the most famous dancers in Asia. What suggested it was a single afternoon, when Jong-in was eight years old, and his father took him to see a ballet. The ballet was “The Nutcracker”, and the boy who watched it did not just enjoy it. He fell in love with it, completely, and he never fell out of love again.

That afternoon set the course of his life. He began to study ballet, then jazz, then hip-hop, and he practised with a seriousness that surprised his teachers. He was not a loud child, and he was not a showy one. He was focused, determined, and quietly obsessed with movement. By the time he was thirteen, he was good enough to be noticed by SM Entertainment, and he was invited to join the company as a trainee. Five years later, he was standing on a stage as the main dancer of a new group called EXO, and he was the first member the public ever saw. This is the story of a boy who watched a ballet at eight, and who spent the rest of his life trying to dance as beautifully as the dancers he saw that day.

Suncheon, Two Sisters, and a Ballet That Changed Everything

Suncheon is a slow, green city, famous for its wetlands, its bay, and its quiet way of life. Jong-in’s childhood belonged to that quiet world. He went to local schools, he played with his sisters, and he spent his free time running, jumping, and moving, the way young boys do. He was not a particularly academic child, and he was not a particularly loud one. He was a boy who liked to move, who liked to test what his body could do, and who was always happiest when he was in motion. His sisters, both older than him, teased him, looked after him, and encouraged him, and the family was close, warm, and supportive.

When he was eight, his father took him to see “The Nutcracker”, the famous ballet about a girl, a prince, and a magical Christmas night. Jong-in had never seen ballet before, and he had no idea what to expect. What he saw changed him. He watched the dancers leap, spin, and float across the stage, and he understood, in a way that an eight-year-old rarely understands anything, that this was what he wanted to do. He did not want to watch dancers. He wanted to be one. He went home that night and told his parents, and they, to their credit, listened. They enrolled him in ballet classes, and they supported him as he began a journey that would take him far from Suncheon.

Ballet is not an easy art for a young boy in Korea, where dancing is often seen as a girl’s activity, and Jong-in faced teasing from other boys. He did not care. He loved the discipline, the control, and the beauty of it, and he practised with a seriousness that impressed his teachers. He learned the positions, the jumps, and the turns, and he built a foundation of strength and flexibility that would serve him for the rest of his career. He later added jazz dance and hip-hop, learning the sharp, powerful moves of street dance alongside the grace of ballet, and the combination became his signature: a dancer who could be both soft and strong, both graceful and fierce.

He was thirteen when SM Entertainment noticed him. He had gone to an audition, he had danced, and the judges had seen enough to offer him a place as a trainee. He was young, he was far from home, and he was entering a world of daily lessons, strict schedules, and fierce competition. But he had something that set him apart: he was not just a pop dancer. He was a trained dancer, with years of ballet behind him, and a body that understood movement in a way that other trainees did not. That training became his greatest asset, and it is the reason his dancing looks different from everyone else’s.

The years of training were long and hard. He practised singing, which did not come naturally to a dancer, and he practised performing, which did not come naturally to a quiet boy. He worked at it steadily, patiently, and without complaint, and he grew into a performer who could sing, dance, and hold a stage. By the time the group was ready, he was eighteen years old, a young man with a dancer’s body and a dancer’s discipline, ready to show the world what he could do.

The First Face of EXO and the Dancer at the Centre

Kai was the first member of EXO that the public ever saw. In late 2011, SM began to introduce the new group with a series of teaser videos, and Kai was the first to appear, dancing alone in a dark studio, his body moving with a power and a grace that made people stop and watch. It was a bold choice. Most groups introduce their singers first. SM introduced their dancer first, because his dancing was that good, and because it told the world exactly what kind of group EXO would be: a group built on performance, on movement, and on stagecraft.

When EXO appeared in public in the spring of 2012, with their opening single “Mama”, released in April that year, Kai was at the centre of the choreography, the dancer around whom the others moved. He was the main dancer, the visual centre, and the performer whose movements defined the group’s style. Fans noticed him immediately. He was tall, handsome, and powerful, and he danced with a control that made even simple steps look extraordinary. People began to talk about him as the best dancer in K-pop, and they have been talking about him that way ever since.

The years that followed were a rush of recordings, concerts, and travel. EXO became one of the biggest boy groups in the world, and Kai grew up in the middle of it. He learned to perform in front of huge crowds, to handle interviews, and to live a life that was never truly private. He also learned to share a stage with many other strong personalities, each with his own dreams and frustrations. He did it the way he did everything: by working hard, by practising until the choreography was perfect, and by letting his dancing speak for him. He was not a loud talker, and he was not a showy personality. He was a dancer, and his dancing was enough.

He also became known for his fashion sense. Kai was chosen as a global ambassador for the luxury brand Gucci, and he appeared in campaigns, at fashion shows, and in magazines around the world. He was the first Korean idol to become a global ambassador for Gucci, and the honour was a recognition of his style, his presence, and his influence. He wore the clothes with a confidence that made them look natural, and he brought a dancer’s grace to every photo. Clothes, for Kai, move the way a dance moves, and he grasped that link without anyone teaching it to him. He moved through the fashion world the way he moved through a dance: with control, with confidence, and with style.

By the end of the decade, Kai had achieved something rare in K-pop: he was respected both as a group member and as a dancer in his own right, and he was respected by dancers as well as by pop fans. He had gone from a boy in Suncheon who loved ballet to a performer whose name alone could fill a concert hall. But his thirties would bring new tests, and the next chapter would be the hardest one yet.

Mmmh, Peaches, Rover, and a Solo Dancer’s Voice

Kai’s solo debut came in November 2020, when he released his first mini-album, “Kai”, with the title song “Mmmh”. The album was a statement of intent. It was not a copy of EXO’s sound. It was Kai’s sound: smooth, sensual, and built around his dancing. The title track was a slow, confident R&B song, and the choreography was built around Kai’s strengths: powerful, graceful movement, with a control that made every step look effortless. It was a success, and it proved that he could hold a stage on his own, without the other members beside him. For a boy who had been a dancer first and a singer second, it was a remarkable achievement.

He followed it with “Peaches” in November 2021, a brighter, sweeter mini-album that showed a lighter side of Kai. The title song was a romantic, playful track, and the choreography was softer, more fluid, and more joyful. It was a different mood from his debut, and it showed that Kai could do more than dance powerfully. He could dance gently, too, and he could sing with a warmth that surprised people who had only heard him in a group. Fans loved it, and critics praised the album for its charm and its variety.

“Rover” arrived in March 2023, and it was his most confident work yet. The title song was bold, rhythmic, and full of energy, and the choreography was sharp, fast, and fiercely precise. It showed a dancer at the peak of his powers, a man who had spent more than a decade on stage and who knew exactly what he could do. The album was a success, and it confirmed that Kai was not just a group member with a side project. He was a solo artist with a real voice, a real style, and a real audience. He followed it with “Wait On Me” in April 2025, after his army duty, a return that showed his fans had waited for him, and that his dancing was as strong as ever.

His solo concerts have become known for their spectacle and their beauty. He designs the stage, he chooses the outfits, and he dances with a power and a grace that makes a large hall feel like a theatre. He sings, he dances, he talks to the audience, and he shows them the full range of who he is. It is a performance that only Kai could give, because it is built on his ballet training, his years of experience, and his deep love of movement. It is a performance that reminds the audience why they fell in love with him in the first place: because he moves like no one else.

He has also continued to perform with EXO, and the group remains a central part of his life. The bond between the members is one of the strongest in K-pop, built over more than a decade of shared work and shared joy. Kai’s role in that bond is the dancer, the centre, the member whose movement defines the group’s style. He is the one the others look to when the choreography is hard, and the one who sets the standard for the whole group. That is a responsibility he carries with pride, and it is one he has never taken lightly.

Andante, SuperM, and the Actor Who Learned on Camera

Acting came to Kai in 2017, when he took the lead role in the drama “Andante”, playing a high school student who moves to the countryside and learns about life, love, and family. It was a gentle, thoughtful drama, and Kai’s performance was praised for its warmth and its sincerity. He was not a trained actor, but he had a natural presence on screen, and he knew how to hold a camera’s attention. The drama was a success, and it opened the door to more acting work.

He followed it with a role in “The Miracle We Met” in 2018, a fantasy drama about a man who wakes up in another man’s body, and with “Spring Has Come”, a Japanese drama in the same year, where he played a young man working in a television studio. Each role was different, and each one showed a different side of him. He played students, workers, and ordinary men, and he played them all with the same honesty and the same care. He did not chase fame as an actor. He chased good roles, and good roles came to him, because directors trusted him to deliver.

In 2019, SM put him in a new group called SuperM, a supergroup made up of members from EXO, SHINee, NCT, and WayV. The idea was to bring together the company’s best performers and take them to the American market. Kai was one of the leading members, and he took on a central role in the group’s performances, dancing with a power that made him stand out even among the best dancers in the company. SuperM released an album, toured the United States, and performed on American television. For Kai, it was a chance to work with dancers and singers from a younger generation, and to show an audience that had never seen EXO what he could do.

He has also appeared on variety shows, where his quiet, thoughtful personality made him a popular guest, and where fans saw a gentler side of the intense performer. He is not a loud entertainer, and he does not try to be funny on command. He is simply himself: calm, polite, and genuinely interested in the people around him. That authenticity is rare on television, and it is one of the reasons fans have stayed loyal to him for so long. They feel that they know the real Kai, not a character invented for the cameras.

What ties all of this together is a simple fact: Kai loves to perform. He loves it in a group, he loves it alone, he loves it on screen, and he loves it on a stage with only a spotlight for company. That love has never faded, even after more than a decade in a demanding industry. It is the reason he keeps working, keeps recording, and keeps performing, long after many of his contemporaries have slowed down. He performs because it is what he does, and because it is who he is.

A Sudden Call-Up, Public Service, and a Return in April

In May 2023, Kai’s career was interrupted in a way that surprised everyone, including Kai himself. He received a sudden call to begin his army duty, with only a short time to prepare, and he enlisted as a public service worker. The news was a shock to his fans, who had expected more warning, and it was a shock to Kai, who had been preparing for a new album and a concert tour. He had to cancel his plans, say goodbye to his fans, and report for duty. It was a difficult moment, and he handled it with the grace and the dignity that have always defined him.

His time in public service lasted about a year and nine months, and he was discharged in February 2025. It was a long time away from the stage, a period of ordinary life after more than a decade of fame. He has said little about it, which is in keeping with his nature. He did his duty, he came home, and he went back to work. There was no drama, no grand statement, only the quiet return of a man who had done what was asked of him. Fans welcomed him back with open arms, and his return was one of the happiest moments of the year for EXO’s fans.

His first release after his return was the mini-album “Wait On Me”, in April 2025, and it was a triumph. The title song was smooth, confident, and full of the dancing that had made him famous, and the album showed that his time away had not dulled his talent. He was thirty-one years old, a veteran of the K-pop world, and he was performing like a man who had finally found his own rhythm. The album did well, and his fans were relieved to see him back, dancing as beautifully as ever.

He continues to perform with EXO when the members’ schedules allow, and the group remains a central part of his life. The bond between the members is one of the strongest in K-pop, built over more than a decade of shared work and shared joy. Kai’s role in that bond is the dancer, the centre, the member whose movement defines the group’s style. He is the one the others look to when the choreography is hard, and the one who sets the standard for the whole group. That is a responsibility he carries with pride, and it is one he has never taken lightly.

Today, Kai is a man in his early thirties who has spent more than half his life on stage, and who still dances with the same grace he had as a boy in Suncheon. He has been the first face of EXO, the main dancer of one of the biggest groups in the world, a solo artist, an actor, and a fashion ambassador. He has done it all with a quiet, steady power that has earned him respect from dancers, singers, and audiences alike. That is a rare achievement, and it is one worth remembering.

Gucci, the Camera, and a Dancer’s Eye for Style

Kai’s work in fashion deserves its own place in this story, because it shows a different side of him. He was chosen as a global ambassador for Gucci, one of the world’s most famous luxury brands, and he was the first Korean idol to receive that honour. He appeared in campaigns, at fashion shows, and in magazines around the world, and he brought a dancer’s grace to every photo. He wore the clothes with a confidence that made them look natural, and he moved through the fashion world the way he moved through a dance: with control, with confidence, and with style.

To Kai, a garment behaves the way a dance step behaves, and he sensed that connection entirely on his own. He knew how to stand, how to turn, how to hold a pose, and how to make a photograph feel alive. Photographers loved working with him, because he did not need direction. He knew what to do, and he did it with a professionalism that impressed everyone who worked with him. He was not just a pretty face in a campaign. He was a performer, and he treated every photo shoot like a performance.

He has also been a popular figure on social media, where his photos and videos have millions of followers. He shares his dancing, his travels, and his daily life with a warmth and an honesty that makes his fans feel close to him. He is not a distant star. He is a real person, with real interests, real friends, and a real life, and he is happy to share it. That openness is rare in K-pop, where many idols keep their private lives hidden, and it is one of the reasons fans love him.

What ties all of this together is a simple fact: Kai is an artist, in the fullest sense. He is a dancer, a singer, an actor, and a fashion icon, and he does them all with the same care, the same discipline, and the same love of beauty. He is a man who sees the world as a stage, and who treats every moment as a chance to create something beautiful. That is a rare and wonderful thing, and it is why his story matters.

My Take:

I have watched many dancers in my life, and I have never seen one quite like Kai. Most pop dancers are fast, sharp, and athletic. Kai is all of those things, but he is also something else: he is graceful, in the way a ballet dancer is graceful, with a control and a beauty that comes from years of training. When he dances, he does not just hit the beats. He flows through them, he bends around them, and he makes the music look like something you can see. That is a rare gift, and it is the reason he has been called the best dancer in K-pop for more than a decade. I think the praise is deserved, and I think history will remember him as one of the great dancers of his generation.

What I admire most about him is the ballet. He started ballet when he was eight years old, after watching “The Nutcracker” with his father, and he never stopped. Ballet is not an easy art for a young boy in Korea, where dancing is often seen as a girl’s activity, and Kai faced teasing from other boys. He did not care. He loved the discipline, the control, and the beauty of it, and he practised with a seriousness that impressed his teachers. That foundation, built when he was a child, is still there in his dancing today. When he leaps, when he spins, when he holds a pose, you can see the ballet in it. It is the reason his dancing looks different from everyone else’s, and it is the reason his dancing will last, long after the fast, sharp moves of pop dance have faded. Ballet is forever, and Kai carries it with him.

I also think about the fact that he was the first member of EXO that the public ever saw. SM introduced him first, in a teaser video where he danced alone in a dark studio, and it was a bold choice. Most groups introduce their singers first. SM introduced their dancer first, because his dancing was that good, and because it told the world exactly what kind of group EXO would be. That is a remarkable thing to say about a young man who was only seventeen at the time. It says that the company trusted him, that they believed in his talent, and that they knew his dancing could carry a whole group. He did not let them down. He carried EXO for more than a decade, and he is still carrying it today.

His solo music deserves more praise than it usually gets. He was a dancer first and a singer second, and it would have been easy for him to release solo music that was all dancing and no singing. He did not do that. He worked on his voice, he chose good songs, and he built a solo catalogue that stands on its own. “Mmmh”, “Peaches”, “Rover”, and “Wait On Me” are not just dance tracks. They are songs, with melodies, with feelings, and with a voice that has grown stronger with every release. I think “Peaches” is especially lovely, because it shows a lighter, sweeter side of Kai, a man who can dance gently as well as powerfully, and who can sing with a warmth that surprises people. That range is the mark of a real artist.

I think about his sudden call-up to army duty in May 2023, and about how hard that must have been. He had been preparing for a new album and a concert tour, and he had to cancel everything, with only a short time to prepare. That is a frightening moment for any performer, and it is especially frightening for a dancer, whose body is his instrument, and who worries that time away will dull his skills. Kai handled it with grace and dignity. He did his duty, he came home in February 2025, and he went straight back to work, releasing “Wait On Me” in April 2025 and proving that his time away had not dulled his talent. That is a brave thing to do, and it is a sign of a man who trusts his craft and his body. He knew that the dancing would still be there when he returned, and he was right.

His work in fashion is another thing I admire, because it shows a different kind of intelligence. He was the first Korean idol to become a global ambassador for Gucci, and he earned that honour not by being famous, but by being stylish, by understanding clothes, and by bringing a dancer’s grace to every photo. Fashion, like dancing, is a form of movement, and Kai understood that instinctively. He knew how to stand, how to turn, how to hold a pose, and how to make a photograph feel alive. That is not a small skill. It is a form of art, and it is one that Kai has mastered. He is not just a pretty face in a campaign. He is a performer, and he treats every photo shoot like a performance.

I also think about his acting, and about how much he has grown as an actor. He was not a trained actor when he took the lead role in “Andante” in 2017, but he played it with a warmth and a sincerity that surprised the drama’s producers. He followed it with roles in “The Miracle We Met” and “Spring Has Come”, and each one showed a different side of him. He played students, workers, and ordinary men, and he played them all with the same honesty and the same care. He did not chase fame as an actor. He chased good roles, and good roles came to him, because directors trusted him to deliver. That is professionalism, and it is the reason his acting career has lasted as long as his music career.

What I love most about Kai is his quietness. He is not a loud talker, and he is not a showy personality. He is calm, polite, and thoughtful, a man who lets his dancing speak for him. That quietness is refreshing in an industry that rewards noise, and it is one of the reasons fans trust him. They feel that they know the real Kai, not a character invented for the cameras. He is a man who does not need to shout to be heard, because his dancing is loud enough. It speaks for him, and it speaks clearly, in a language that everyone can understand, no matter what country they come from or what language they speak. Dance is a universal language, and Kai speaks it fluently.

I think about his future, and I am excited about it. He is in his early thirties, an age when many dancers begin to slow down, but Kai shows no sign of slowing down. He is releasing new music, performing with EXO, acting, and exploring new projects in fashion and beyond. He is a man who has built a career that is entirely his own, and he is still building it. I believe his best work may still be ahead of him, because he is the kind of artist who gets better with age, who learns from every experience, and who never stops growing. I hope he keeps dancing for many years, because the world needs dancers like him.

In the end, Kai’s story is about a boy who watched a ballet at eight, and who spent the rest of his life trying to dance as beautifully as the dancers he saw that day. It is about discipline, about patience, and about the power of movement to say what words cannot say. It is about a dancer who became a star, a singer, an actor, and a fashion icon, and who did it all with a quiet, steady grace. I have watched him for years, and I still find something new in his dancing every time. That is the sign of a true artist. He does not repeat himself. He keeps learning, he keeps changing, and he keeps moving. That is the best thing I can say about a dancer, and I think it is the best thing I can say about a person.

I want to add one final thought, about the way Kai treats the people around him. His fellow members have said many times that he is the one who sets the standard for the group, who practises the hardest, and who inspires the others to work harder. That is not the work of a star. It is the work of a leader, and a brother. Fame can make people selfish, and it can make them forget the people who helped them. Kai has not forgotten. He still works hard, still practises, still sets an example for the younger members, and still treats his fans with respect. That dedication is the foundation of everything else he does, and it is the reason his fans love him as a person, not just as a performer. Talent fades. Dedication lasts, and Kai has it in abundance.

I also want to talk about the discipline behind the beauty, because people who watch Kai dance sometimes think it comes naturally to him, as if he were born moving that way. He was not. He was born with talent, yes, but talent without work is nothing, and Kai has worked harder than almost anyone in K-pop. He started ballet at eight, he trained for five years before he debuted, and he has practised every day since. His body is an instrument that he has tuned for more than twenty years, through pain, through tiredness, through injuries that fans never hear about. When you see him leap across a stage and land without a sound, you are seeing twenty years of practice in a single second. That is what dedication looks like, and it is a lesson for anyone who thinks that great artists are simply born great. They are not. They are made, day by day, in studios where nobody is watching.

Another thing I admire is how he has handled being the centre. In EXO, Kai is the dancer around whom the choreography is built, and that is a heavy responsibility. If he makes a mistake, the whole formation falls apart. If he is tired, the whole performance suffers. He has carried that weight for more than a decade, and he has never complained about it. He has simply shown up, practised, and performed, again and again, with a consistency that is remarkable. That is the mark of a professional, and it is the reason his fellow members trust him so completely. They know that when Kai is on stage, the dancing will be right, and they can focus on their own parts. That trust is the foundation of a great group, and Kai has earned it.

I think about young dancers who watch his videos today, in bedrooms and studios all over the world, trying to copy the way he moves. What they are really learning is not a set of steps. They are learning that dance can be a language, that a body can say things that words cannot, and that beauty and power can live in the same movement. That is a gift Kai has given to a whole generation of dancers, and it will outlast any single song or album. Long after the charts have moved on, dancers will still be studying his performances, still trying to understand how he made something so difficult look so easy. That is a legacy worth having, and it is one that few performers ever achieve.

One last thought about Kai, and it is about the boy in Suncheon who watched “The Nutcracker” at eight and fell in love with ballet. That boy is still there, inside the man who fills arenas today. Every time Kai leaps, every time he spins, every time he holds a pose until the audience holds its breath, he is keeping a promise he made to himself as a child: to dance as beautifully as the dancers he saw that day. He has kept that promise, and he keeps it still. I hope he keeps it for many years to come, because the world is better for it.
