He wasn't in love with Seo-in. He did that because he knew Seo-in was in love with Yeongwoon so he wanted to ruin them both starting with Seo-in. He's so fvcked up that he doesn't want Seo-in to have at least one friend or feel love, he wanted Seo-in to be just his shadow.
idk abt jaewon being in love with seo-in. i think it's bcs he's a controlling brat and he wants to fuck with seo-in’s life (make it hell). he’s got superiority complex or idk. another assumption is that he's acting that way cuz he knows he’s got a shorter life and is acting like a bitch out of bitterness lol.
I could smell it from a mile away. He had this twisted feelings of attraction to Seo-in that's why he wanted to control him so bad. What a freak
Honestly, it’s not love. He’s a kid, too. He probably felt like his mother was trying to replace him, or have a stand-in for when he inevitably dies. His hatred was tied into the bitterness he felt toward his situation—probably.
I mean there are a gazillion ways of torturing him but he wanted seoin to kiss him. this shows an inner attraction he cannot accept imo.
lowkey jaewon was obsessed and in love with seo-in whick shows he’s a really sick fuck both mentally and physically lol it disgusts me how he tortured seoin and use his last years like that
