Give him a break... He is young so he can developed his acting! I love him at Island or True Beauty, for example. He is not only a pretty face! I've seen other Korean actors/actresses older than him and also worst than him.
If he apologized and she couldn't find it in herself to forgive him, she shouldn't have gone back or tried to…
I 'm not an hardcore fan of anyone. Never have been! I just can think for myself and my long life experience teach me that in a relationship if someone cheat the blame is not only from the cheater....Cheating someone is not just pshysical ... And hen you discover that your partner has cheated you don't come to publicize ate internet... you just leave and move on if you don't want to forgive
