Seo In-guk is an actor, singer, and reality show star from South Korea. He gained instant and immense recognition after winning a singing reality show in 2009. Since then, there has been no looking back for this talented youngster. Soon, he was introduced in movies and television series. Seo’s career graph has travelled only northwards since then. A career spanning less than a decade in the entertainment industry is hardly a mark of greatness but if the quality of Seo’s work and his popularity are any indication, he will slowly but surely reach that mark. Immense talent coupled with childlike innocence is what makes Seo stand out in the crowd. Given his appearance and ancestry, one might think that his stardom is regional but that would be a gross understatement. Seo has attained global stardom at quite a young age and from what it appears, it is likely to increase with time.

Childhood & Early Life
  • The year 2009 was a breakthrough one for Seo. He was fresh out of college when he went to the audition of ‘Superstar K’, expecting another refusal. However, luck finally smiled on him and he was selected as a contestant of the music reality show which was itself in the inception stage. He went on to win the show and in the process created history as the winner of the inaugural edition of the show.
  • Recognition came almost overnight. Suddenly everyone was talking about him and offers for music albums and other things came flooding in. He did a number of recordings, both singles as well as albums. He also did non-musical stuffs such as photo-shoots and television interviews, which increased his recognition even more.
  • However, everything was not bright and sunny for Seo at the beginning of his career. With the massive recognition he got overnight, came in a barrage of criticism and rumors. It was rumoured that he had done a plastic surgery, a rumor that was never substantiated.
  • Seo made his acting debut in 2012 when he was cast in a supporting role in KBS’ ‘Love Rain’. The film was a massive hit, especially overseas.

  • A chance to play the lead came soon after in the second half of 2012 with ‘Reply 1997’, a nostalgic television series, which announced the arrival of Seo on the big stage. The series was about the life of six friends in two phases - one when they are all young and the other 18 years later. The series was quite successful with the season finale generating the highest rating for a Korean cable drama. Seo did remarkably well and was highly praised by the general public and the critics again.

Later that year, he also appeared in a drama series called ‘The Sons’ (alternatively known as ‘Rascal Sons’)
