Oh man 4 years? I know I saw him in several dramas like My love from stars, Blood and Cinderella and the our knights and loved his acting and I was thinking why he was not into dramas lately ... Welcome back bro
i knew i have seen him some where now i confirmed it ( Long time no see )
When suddenly he came in Choco Milk Shake I was like I def saw him somewhere but where then I rushly come here and saw this and got to know that I already saw him a long time ago xd
