You forgot in S1 yeongwoon literally run away from home and he also left seoin . In S2 we already see how seoin want to live together yw, he also made plans after their graduate from school. When he already start falling in love with yw at that time their relationship are ruin bcs yw saw their kiss, and in S1 we see how jaewon abuse yw to the point jaewon mother cover up and bribe yw father. I think those abusing make yw runaway after their school end, and it took a toll and seoin feelings that yw left him.that’s why he become like that manipulative, manwhore he is heart breaking to the point he become problematic.

You literally underestimate that sometimes hearbreak can ruin people life? We see that seoin literally doesn’t have no one on his side. And YW are the first one that been his friends and now he finally realised that he loves yw. Seoin Being industry are just a runaway from jaewon if you still remember previous of chapter he doesn’t socialise much cause he literally focusing on yw alone. He pov literally center around yw tho. Its makes sense why his behaviour are like that when he grown up after yw left him
Jaewon is genuinely such a messed up guy, no wonder he had to be killed off by a disease. Unfortunately, I don’t understand how Seoin turned out the way he is as an adult. He’s literally not mentally all there, he has a severe drug/sex addiction for who knows how many years. Not only that, he sexually assaults Yeongwoo on multiple occasions. It doesn’t make sense how his life went that morally downhill when he cared about Yeongwoo’s well-being so much.
