While what he did is unforgivable, I'll admit I'm proud of him (note that I use "proud" very loosely here) for realizing what he did wrong. He's not upset he was caught. He's upset he did it. He's not regretting it just because he lost his girlfriend, but also because he caused her and Min pain. A lot of people don't, so I'm glad he did.
Honestly, he's going to get a happy ending whether he ends up with her or not, since time heals all wounds, so in retrospect, it doesn't really matter if they get back together or not, lol.
He does get one ;-;
yeah, people always get a happy ending no matter how sh*tty they are. i would know, cos i have a couple of exes. lolol it's good he realized what he did was wrong, but the hurt he caused min and got with him just to keep him from chun sam/looked like his gf to me is too much. min already has been going through so much crap on his own, not being loved by his father, etc., this is why i hate that character. plus, i know what it's like to be cheated on it.
fine if they have closure for their story, but if that little sh*thead and his gf get a happy ending, i'm gonna be pissed. cheaters don't deserve happy endings, especially ones that play with innocent and unsuspecting people who just happens to look like a gf/bf. grrr
