After that, however, he halted his activities for one year to think about his identity and the path of acting without being influenced by popularity. Returning with independent film Boys of Tomorrow (2006) and family-comedy Skeletons in the Closet (2007), he attracted a lot of attention of critics and viewers as a promising newcomer.

The next year, he achieved considerable critical and public acclaim for his brilliant portrayals of both the villain in big-hit action film Veteran (2015) and a tragic prince in historical film The Throne (2015). This also led to gaining wider recognition as an established actor when he acted the protagonist in 50 episodes of Six Flying Dragons (2015) for six months. During this period, as he gained a huge popularity and received various accolades, the media called this phenomenon ‘Ah-in Era’. Especially, he won the Best Actor award in the Blue Dragon Film Awards, which means that he is the first actor to win in this category under 30 in fifteen years.
