Season 2 already proof the confusion we had on Season 1. Jaewon and seoin are not fall in love the kiss probably jaewon scheme to make yeongwoon stay away from seoin.
For sure Jaewon bullying Yeongwoon before because he know that seoin love yeongwoon. And he did that bcs he want to get rid off people who seoin love and make sure nobody on his side. This is what i think when reading the latest chapter.

now i know why jaewon bullying yeongwoon its probably because he want to get rid of people who seoin love and yeongwoon are one of them.
the fact the whole family especially his momare fucked up instead of addressing the root of the problem, she begged seo-in to keep up the facade, as she needed the appearance of a happy family to feel better. she allowed her unwell biological son to hurt seo-in because his well being mattered less to her than her own need to act like she had twin sons. but using real children as emotional support tools to fill a void is not just selfish, it’s abusive
Seoin makes plan to use yeongwoon for revenge on jaewon. maybe after this meeting he found his light in his dark world in the process and he ended up have feeling with yeongwoon
