The brother (Jaewon) is bottom right? I don't know but I think the brother jaewon likes Seo-in that's why he wanted him to leave their family and since he's adopted eventually end up becoming his younger brother, he can't like Seo-in that's why he bullies him 'til he give up and leave the family so in that way the brother can pursue his love with seo-in?.. Or maybe not..But if the scenario is like this it would be a lot better than just bullieng Seo-in because he hates him or jealous of him..
I've gone insane, sick in the head fr.. I've just read lot of bl that have a plot/drama is like this that's why I think like this Lol the delusions~ because the brother jaewon really has pretty face, such a waste of face to be a fvckin jerk HAHAHAHA (a pity him tho, I think he's just another lonely guy seeking attention/affectiom or not? But yeh I like jaewon's face.. Pity he died cause it would be better if he just apologize to seo-in and Yeongwoon and then become a better person, find some green flag seme around so that we could have a side couple or something)
He simply doesn't have emotional intelligence or EQ at all :/
He's looking good here tho,,,, but ACKKKK! idk he's still fvckup!!
It's the first time that I'm so ever satisfied with these kind of story's ending WHAAAAAA!! there's even a baby!! I'm so happy~
I mean who cares??
