Rowoon: The Life Story Behind Korea's Tall Star
In this post
Rowoon is one of the tallest and most recognisable young actors in Korea, and his journey is unusual. He did not start as an actor. He started as an idol, a singer in the boy group SF9, performing on big stages in front of thousands of fans. He was the lead vocalist, the tallest member, and one of the most popular faces in the group. But he wanted more than singing. He wanted to act, and he worked hard to prove that he could. In 2019, he starred in Extraordinary You, and the world saw that he was not just an idol trying to act. He was a real actor, with warmth, humour, and a natural talent for the screen.
Since then, he has led dramas like The King’s Affection, Tomorrow, Destined With You, and The Matchmakers, and he has become one of the most popular young actors in Korea. In 2023, he made a big decision. He left SF9 to focus on acting full time, a choice that surprised many fans but showed how serious he was about his new path. In 2025, he starred in The Murky Stream, a historical drama on Disney+, proving that his career as an actor is still growing.
This is the story of how a boy from Seoul became an idol, and then became an actor, and how he is still writing the next chapter of his life. It is a story about height and looks, but it is also a story about hard work, patience, and the courage to change direction.
Growing Up in Seoul
Rowoon was born on 7 August 1996 in Seoul, South Korea, with the birth name Kim Seok-woo. Seoul is a huge, fast city, full of noise, light, and pressure, and growing up there is very different from growing up in the countryside. He grew up in an ordinary family, and his childhood was normal in most ways. He went to school, played with friends, and dreamed the dreams that young people dream. There was nothing in his early life that pointed clearly toward fame.
He was a tall boy, and he kept growing. As a teenager, he stood out because of his height, and people noticed him. He was also handsome, with a warm smile and a gentle manner, and those qualities would later help him in his career. But height and looks alone do not make a star, and Rowoon knew that. He worked hard, studied, and took his training seriously, because he wanted to be known for his talent, not only for his appearance.
He has not shared many details about his childhood in public, and he has kept his family life private from the start. What is known is that he became interested in performing while he was young, and that he joined FNC Entertainment as a trainee. Becoming a trainee in Korea is a serious commitment. It means years of training in singing, dancing, and performing, with no guarantee of success. Rowoon accepted that challenge, and he trained hard for years.
As a trainee, he learned how to sing, how to dance, and how to perform on stage. He also learned discipline, teamwork, and how to handle pressure. The training was hard, and many trainees give up. He did not give up. He kept working, kept improving, and kept believing that his time would come. That belief carried him through the hardest years, and it is one of the reasons his later success has lasted.
By the time he was twenty, he was ready to debut. He had the training, the looks, and the motivation to succeed. He did not expect fame to come quickly. He expected to work hard, and he was ready for it. That attitude would carry him through the years that followed, and it would help him when he decided to change direction and become an actor.
Debut With SF9 and Life as an Idol
Rowoon made his debut in October 2016, as a member of the boy group SF9, under FNC Entertainment. He was the lead vocalist, and he was one of the tallest members of the group. SF9 was a nine-member group, and they debuted with a strong, energetic style. They performed on music shows, released albums, and built a fan base in Korea and abroad. Rowoon quickly became one of the most popular members, because of his height, his looks, and his warm personality.
Life as an idol is hard. It means long hours of practice, constant travel, and little privacy. Idols must sing, dance, and perform perfectly, night after night, in front of audiences that expect the best. Rowoon learned to do all of that, and he did it well. He performed on big stages, met fans from many countries, and learned what it means to be a star. That experience gave him confidence, and it taught him how to handle fame.
He also learned how to work as part of a team. In a group of nine, no one succeeds alone. You must listen to the other members, support them, and trust them. Rowoon became known as a kind and reliable member, and his fellow members trusted him. That reputation followed him into acting, and it is one of the reasons directors like working with him. He is a team player, and he makes everyone around him better.
During his time with SF9, he also began to act. He took small roles in dramas, learning how to act in front of a camera while still performing with the group. It was a busy life, with music and acting at the same time, and it required a great deal of energy. He managed it well, and he grew as both a singer and an actor. He was building two careers at once, and he was doing it with care.
The idol years gave him something else too, a large and loyal fan base. Fans who loved him in SF9 followed him into acting, and they supported his dramas with great enthusiasm. That support helped him when he took on leading roles, because he already had people who believed in him. He has never forgotten those fans, and he has thanked them many times for their support.
First Acting Roles and Learning the Craft
Rowoon began acting in 2017, while he was still active with SF9. His acting debut came in the drama School 2017, where he played Kang Hyun-il, a student. It was a small role, but it was in a popular drama series, and it gave him his first taste of working on a television set. He learned how a drama is made, how to work with other actors, and how to act in front of a camera. For a young idol, that was a new world, and he learned it quickly.
In 2018, he appeared in About Time, and then in Where Stars Land, playing supporting roles that gave him more experience. Each role taught him something new, and each one made him a better actor. He learned how to listen to other actors, how to make a small part feel real, and how to wait for his chance. Waiting is a large part of an actor’s life, and Rowoon learned to wait without giving up.
He also learned that acting is different from performing on stage as an idol. On stage, you perform for a large audience, and you must be big and energetic. On camera, you must be small and honest, and the camera will see everything. He learned to do less with his body and more with his eyes, and he learned that a small change in the face could say more than a big gesture. These were not easy lessons, but he learned them well.
During these early years, he also faced a challenge that many idols face. People did not always take him seriously as an actor, because they saw him as a singer first. He had to prove himself, again and again, in every role. He did that by working hard, by preparing carefully, and by giving every role his full effort. He did not complain about the doubt. He answered it with his work, and his work spoke for itself.
By 2019, he had the skill, the experience, and the trust of directors. What he needed was a leading role that would show the world what he could do. That role came in Extraordinary You, and it changed his life completely.
Extraordinary You and the Breakthrough
In 2019, Rowoon starred in Extraordinary You, playing Haru, a mysterious young man who helps the main character discover that she is living inside a comic book. The drama was a fantasy romance, and it became a huge hit, especially with young viewers. He played Haru with warmth, humour, and a quiet sadness, and audiences fell in love with him. The drama made him famous as an actor, and it proved that he was not just an idol trying to act. He was a real actor.
The role suited him well. Haru was tall, handsome, and kind, but he was also a character who did not know who he was, and who was searching for his place in the world. Rowoon played that search with honesty, and viewers felt it. He made the fantasy feel real, and he made the romance feel true. That is a hard thing to do, and he did it beautifully. The drama won him newcomer honours, and his popularity grew enormously.
What made the role so powerful was its warmth. Haru was a character who cared deeply, who protected the people he loved, and who was willing to sacrifice himself for them. Rowoon played that caring with great sincerity, and audiences responded to it. He was not acting like a star. He was acting like a real person, and that realness is what made the drama work. Fans around the world loved him, and his name became known in many countries.
After Extraordinary You, his career changed completely. He was offered leading roles, and he was offered the kind of parts that only stars get. He became one of the most popular young actors in Korea, and his face was everywhere. He handled the fame with grace, staying humble and hard-working, and he chose his next roles carefully. He did not rush into anything. He waited for roles that would let him grow, and that patience paid off in the years that followed.
It is worth remembering that he was only twenty-three when Extraordinary You made him famous as an actor. He had spent three years in SF9 and two years in small acting roles, and all of that had prepared him. When the world finally saw him as an actor, he was ready, and the world has been watching him ever since.
The King’s Affection, Tomorrow, and Leading Man Status
After Extraordinary You, Rowoon took on leading roles that proved he was more than a one-hit star. In 2021, he starred in She Would Never Know, playing a young man in love with an older colleague, and then in The King’s Affection, playing Jung Ji-woon, a teacher who falls in love with a king who is secretly a woman. The King’s Affection was a historical drama, and it was a major success, winning awards and praise. His performance was loved by viewers, and he won newcomer honours for the role.
The King’s Affection was important because it showed that he could lead a historical drama, a genre that is difficult and demanding. He played Ji-woon with warmth, loyalty, and a quiet strength, and he made the character feel real in a world of palaces and secrets. It was a different kind of role from Extraordinary You, and it showed his range. He could be a fantasy hero and a historical teacher, and both felt true.
In 2022, he starred in Tomorrow, playing Choi Jun-woong, a young man who becomes a grim reaper and helps people who are struggling with life. The drama was about life, death, and hope, and it asked him to show deep feeling. He played Jun-woong with sincerity and heart, and the drama was praised for its warmth. It was a serious role, and it showed that he could handle stories about pain and healing, not just romance.
He also continued to work with SF9 during this time, balancing his music career with his acting career. It was a busy life, with concerts, albums, and dramas all at once, and it required a great deal of energy. He managed it well, but it was clear that acting was becoming his main focus. He was growing as an actor, and he wanted more time to grow.
By the end of 2022, he had done something remarkable. He had led three very different dramas in three years, and he had been good in all of them. He was no longer just an idol who acted. He was a leading actor, and directors were lining up to work with him. His future looked bright, and it was about to take a big turn.
Leaving SF9 and Choosing Acting
In September 2023, Rowoon made a big decision. He left SF9 to focus on acting full time. It was a surprising announcement, and it made headlines in Korea. Fans were sad to see him leave the group, but many of them understood. He had been an idol for seven years, and he had become a successful actor. He wanted to give acting his full attention, and he could not do that while also working as an idol. It was a brave choice, and it showed how serious he was about his new path.
Leaving a group is never easy. It means saying goodbye to members who have become like family, and to fans who have supported you for years. Rowoon handled the announcement with grace, thanking his members and his fans, and promising to work hard as an actor. He did not speak badly about anyone. He simply said that he wanted to focus on acting, and that he hoped fans would support him. Most of them did, and they followed him into his new career.
After leaving SF9, he starred in Destined With You in 2023, playing Jang Shin-yu, a lawyer who is cursed and who falls in love with a woman who holds the key to his fate. The drama was a fantasy romance, and it was a success. He played Shin-yu with charm and warmth, and audiences loved him for it. It was his first drama after leaving the group, and it proved that he could succeed as an actor on his own.
In the same year, he starred in The Matchmakers, playing Shim Jung-woo, a young widower who becomes a matchmaker in the Joseon period. The drama was a historical comedy, and it showed a lighter side of him. He played the role with humour and energy, and it was loved by viewers. It was a different kind of role from Destined With You, and it showed his range again. He could be a modern lawyer and a Joseon matchmaker, and both felt true.
The decision to leave SF9 was a turning point in his life. It was a risk, but it was a risk that paid off. He became a full-time actor, and he has continued to grow since then. His story shows that sometimes you must leave something good behind in order to chase something better, and that takes courage.
The Murky Stream and the Next Chapter
In 2025, Rowoon starred in The Murky Stream, a historical drama on Disney+, playing Si-yool, a man who becomes involved in the dark world of the Joseon period. The drama was a big production, with a large cast and a serious story, and it showed a more mature side of him. He played the role with a quiet strength, and it was praised by viewers. It was a sign that he is growing as an actor, and that he is ready for more serious, adult roles.
The Murky Stream was important because it was his first major project after leaving SF9, and it was on a global streaming platform. It reached viewers around the world, and it showed that his fame as an actor is growing beyond Korea. He is no longer just a young idol turned actor. He is a leading man in global drama, and his name is known in many countries. That is a remarkable journey, and it is still going.
He has also expressed a wish to take on more varied roles in the future. He has said that he wants to challenge himself, to play characters he has never played before, and to keep growing. That attitude is the mark of a serious actor, someone who does not want to stay in one place. He wants to explore, to learn, and to surprise his audience. That is a good sign for his future.
His fan base continues to grow, in Korea and around the world. Fans love his acting, his height, his smile, and his personality, and they follow his work closely. He has become one of the most popular young actors in Korea, and his name is now known in many countries. That is a remarkable achievement for a young man from Seoul, and it is still going.
What comes next for him is open, and it is exciting. He could become a major film star, a leading man in global dramas, or both. What is clear is that he has the talent, the work ethic, and the humility to keep growing. The world is watching, and he is ready for whatever comes next.
A Star Who Chose His Own Path
Looking back at Rowoon’s life so far, the most striking thing is the courage of his choices. He became an idol, and then he chose to become an actor. He became a successful actor, and then he chose to leave his group to focus on acting. Each choice was a risk, and each one paid off. He has shown that a career is not something that happens to you. It is something you choose, step by step, and that takes bravery.
He has also shown that an idol can become a serious actor, if they work hard enough. Many idols try to act, and many of them fail, because they do not take the craft seriously. Rowoon took it seriously, and he proved himself, role by role, until no one could doubt him anymore. That is a lesson for anyone who wants to change direction in life. You must work hard, you must be patient, and you must prove yourself with your work.
For young people who dream of performing, his life is a lesson. Start where you are, work hard, learn the craft, and do not be afraid to change direction. Rowoon did all of that, and he became a star. His story is still being written, and his best work may still be ahead of him. That is an exciting thought, and it is why so many people are watching him.
My Take:
I want to start with something honest about Rowoon, and it is that I did not expect an idol to become this good an actor. I have seen many singers try to act, and most of them are not very good, because acting is a different skill from singing. Rowoon is different. He worked hard, he learned the craft, and he became a real actor. When I watched him in Extraordinary You, I forgot that he was an idol. I saw only Haru, a young man who cared deeply and who was searching for his place in the world. That is the highest praise I can give an actor, that I forgot who he was and saw only the character.
I also think about his height, because it is one of the first things people notice about him. He is very tall, and he stands out in every scene. But I think his height is both a gift and a challenge. It is a gift because it makes him memorable, and it makes him look like a leading man. It is a challenge because it can make him seem distant, like someone from another world. What I admire is that he overcomes that challenge with warmth. He plays characters who are kind, funny, and human, and that warmth brings him close to the audience. He does not let his height make him cold. He lets his heart make him warm.
His performance in Extraordinary You is the one I think about most. He played Haru, a character who did not know who he was, and who was trying to find his place. I think many young people feel that way, lost and searching, and he made that feeling real. He played Haru with a quiet sadness, and with a deep kindness, and I felt both. I think that is a beautiful performance, because it speaks to something universal. We are all searching for who we are, and Haru’s search felt like our own.
I also want to say something about The King’s Affection, because it showed a different side of him. He played a teacher in a historical drama, and he had to be serious, loyal, and strong. It was a difficult genre, with palaces, costumes, and old language, and he handled it well. I think that takes discipline, because historical drama asks the actor to forget the modern world and live in the past. He did that, and he made it look natural. I was impressed, and I think it proved that he is not limited to modern romance.
His decision to leave SF9 is something I think about a lot, because it takes great courage to leave a successful group. He had been an idol for seven years, and he had fans, fame, and a secure career. To leave all of that and focus on acting was a risk, and many people would not have taken it. He took it, and I respect him for it. It tells me that he knows what he wants, and that he is willing to give up something good for something better. That is a brave choice, and it is one that many people are afraid to make in their own lives.
I also admire the way he handled the announcement. He did not speak badly about anyone. He thanked his members, thanked his fans, and promised to work hard. That is a graceful way to leave, and it shows his character. He is a kind person, and he treats people with respect, even when he is making a hard decision. I think that kindness is part of why his fans stayed with him, and why they continue to support his acting career.
His work in Tomorrow also moved me, because it was about life and death, and about helping people who are struggling. He played a grim reaper who helps people in pain, and he played him with sincerity and heart. I think that is a hard role, because it asks the actor to show deep feeling without becoming sentimental. He did it well, and the drama was praised for its warmth. It showed me that he can handle serious stories, not just romance, and that is important for his future.
I also think about his looks, because it would be dishonest to ignore them. He is a handsome man, and his looks have helped his career. But looks alone do not make a career last, and they do not make an actor good. What makes him good is that he does not rely on his looks. He acts, and he acts with care. I have seen handsome actors who cannot act, and their careers fade quickly. Rowoon can act, and that is why I believe his career will last long after his youth has passed.
I also want to mention his work in The Murky Stream, because it shows how much he has grown. He played a more mature, serious character, in a dark historical drama, and he handled it well. I think that is a sign of his future. He is no longer a young idol. He is a man in his late twenties, with more life experience, and that experience will deepen his acting. I look forward to seeing the roles he takes in the next ten years, because I think they will be deeper and richer than the ones he took before.
If I had to name one lesson from his life, it would be this: do not be afraid to change direction. He was an idol, and he became an actor. He was in a group, and he chose to go solo. Each change was scary, and each one made him grow. I think many people stay in a job or a life that no longer fits them, because they are afraid to change. Rowoon changed, and he became better for it. That is a lesson I want to remember, and I think it is one that many people need to hear.
I also think his story teaches us about the value of hard work. He trained for years as an idol, and he trained for years as an actor, and he never stopped working. That is not glamorous, and it is not easy, but it is the truth of any career. Talent helps, but work is what makes talent last. Rowoon has worked hard, and his work has paid off. I think that is a hopeful message for young people who are still training, still learning, and still waiting for their chance.
I also think about the fans who love him, and I understand why they love him. He is talented, tall, handsome, and kind, and he treats his fans with respect. In a world where many stars are distant, he feels close. That closeness is not an act. It is who he is, and it is part of why his fame feels warm instead of cold. I think that is a special quality, and I hope he keeps it.
There is a sadness in his story too, and I do not want to ignore it. The sadness is in leaving SF9, in saying goodbye to members who had become like family, and to a life he had known for seven years. I do not know his private feelings, and I will not invent them, but I know what leaving feels like. It is exciting and painful at the same time, and it changes you. I think that change is visible in his acting, in the depth and the maturity he brings to his recent roles.
I also learn from the way he chooses his roles. He does not choose the easiest path. He chooses stories that matter to him, stories about love, about history, about life and death, and he gives each one his best. That choice tells me that he thinks about his work deeply, and that he wants his work to mean something. I think that is the mark of a serious artist, someone who does not just want to be famous, but wants to say something with their work. Rowoon wants to say something, and I am listening.
When I think about his future, I feel hopeful. He is twenty-nine, and he has already done so much. He has the talent, the training, and the fame to become one of the great Korean actors of his generation. I look forward to seeing what he does next, whether it is a film, a drama, or something completely new. I know that whatever it is, he will bring his honesty, his hard work, and his warmth to it, and I know I will want to watch it.
I also think about the young people who might read his story and dream of performing. If you are one of them, I hope you learn the right lesson from him. Start where you are, work hard, learn the craft, and do not be afraid to change direction. Fame may come fast, or it may come slow, but if you are ready, it will become a career. Rowoon was ready, and his story proves that the long road and the fast road can both lead to the same place, if you walk them with honesty.
I also want to say that I enjoy the way he moves between genres. He has done fantasy, history, romance, and drama, and he has been good in all of them. That is not easy. Many actors find one genre and stay there, because it is safe. He has not stayed safe. He has tried new things, and he has taken risks, and those risks have made his career interesting. I think that is the mark of a true artist, someone who does not stop learning and does not stop growing.
I also think about the people who work with him, the directors, the writers, and the other actors, because they are the ones who see the real man every day. From everything I have read, they speak about him with respect and affection, and that tells me a lot. It is easy to be kind when the cameras are on. It is much harder to be kind every day on a long shoot, when everyone is tired and the work is hard. The fact that people who work with him praise him tells me that his kindness is real.
Finally, I want to say that I am glad a young actor like Rowoon exists. In a busy world full of noise, his work is warm, honest, and full of heart. He plays many different men, and each one feels real. I think that is the best kind of acting, the kind that makes you believe in the person on screen. He has that gift, and I believe he will keep it for many years to come. I look forward to watching his career grow, and I hope he never loses the warmth that makes him special.
I also think his story reminds me that the world is changing, and that young people from ordinary cities can now reach the whole world. He came from Seoul, and he became famous in many countries, because of his talent and because of streaming. That is a hopeful message for young people everywhere. You do not need to be born in the centre of the world to reach the world. You need talent, hard work, and a chance, and Rowoon had all three.
The last thing I will say is simple. I like Rowoon because he is real. He is real in his acting, real in his choices, and real in the way he lives his life. That realness is rare, and it is precious. I hope he keeps it, and I hope he keeps working for many more years, because the world needs more actors like him.
I also believe that his best work is still ahead of him. He is twenty-nine, and he has just begun his career as a full-time actor. He has more life experience now, and more maturity, and that will show in his acting. I think the roles he takes in the next ten years will be deeper and richer than the ones he took in his twenties, and I am excited to see them. He has the potential to become a great actor, not just a popular one, and I believe he will get there.
One more thought stays with me. I think the actors who last are the ones who keep learning, and Rowoon is clearly one of them. He takes different roles, he works with different directors, and he is not afraid to fail. That willingness to keep learning is what will carry him through the next twenty years, just as patience carried him through the first ten. I will be watching, and I will be cheering for him.
