There is no death brutal enough for that shithead of a "father."
I don't think Han-Gun was cheating. I'm sure it'll turn out to have been a friend or a cousin or something. But it was so easy for Won to jump to that conclusion because secretly he's been waiting for it to fall apart. On some level he doesn't believe that Han-Gun's affection or support could be genuine because he's grown up being beaten and belittled by the person who's supposed to care about him the most. It felt too good to be true, so it was easy to believe it really was - to confirm his belief that he doesn't deserve to be happy or loved. Trust issues don't cover it.
WOW. Okay I think it's so vital that Yui heard it directly from Yuha's mouth, though. If Hyun - or anyone - had tried to talk to him about it, I think he would've instinctually rejected whatever he said out of guilt and brainwashed loyalty to his brother.
