Honestly I think Jun is starting to slowly realize that deep down. But doesn’t want to admit it. Han Junwoo actions aren’t ok. It’s trash. He’s garbage. So that’s why he keeps reassuring to himself, him helping Tae San is so he keep up “nice Jun.” I mean Jun isn’t perfect; but he’s not heinous
I don’t know how Jun is still attracted to him. The guy is a huge loser. Beating up someone for attention? Desperate and lame.
