Well you will gonna hate me for saying this at least someone who did something even it's just bare minimum is better. taegu helped YW with bare minimum, Seoin was busy being all angsty only thinking about his feelings, his trauma, even though he knew how abusive YW's father was and how he's the one who dragged YW into his problematic family consciously just to get back to his evil step bro. Seoin still needs room to grow to be at least good ML for YW

Seoin should be blamed for his actions as an adult (the SA), but not as a kid. He was also 15/16 at the time, just a baby, there was pretty much nothing he could do to help YW out, yet he did help YW with his dad. Are we forgetting all the times Seoin whisked YW away to his house/let him stay over so his dad could cool down? Also, you can’t blame Seoin for his psycho brother’s actions.Yes, he stirred the pot between his brother and YW, but the brother already hated YW

I'm saying his first impression (as an adult) and first assumption of seeing YW again is "you are all fine running away from your problem while I'm stuck here in the past with my trauma and you left me behind" he's 'blaming' yw indirectly from quickly moving on and not contacting him lol, even though he knew yw dad is super abusive, but he let that thoughts consume him to the point he antagonize yw inside his head. He only realized his mentality is wrong after seeing yw medication and realized that he can't 'hate' yw as he's still in love. He stopped wanting to mess with yw for his petty reason, bc he finally realized yw isn't fine at all
Literally MC and ML are the only good people in this story and it's baffling how adults failed them again and again and again
