Basically both sangwoo and his father was obsessed with taewon to begin with. As of sangwoo's obsession was due to the care and gentleness taewon gave him, which his omega father couldn't give him, as for them sangwoo was just toy to get close to sangwoo's father, which they couldn't succeed in getting his heart in hold. Taewon was the who captured that feelings from both sangwoo and his father, as it was seen in previous chapters both of their crazy in love feelings towards taewon. For sure sangwoo's actions doesn't being forgiven for his obsession he has, it's more like he don't wanna let it go, like the way when taewon embraced him when they first met and protected him when accident happend it kind of made sangwoo hard to let go of taewon . I would like to know how does sangwoo's father fall for taewon, cause he mentioned on not be living religion but decided to pretend for taewon, I do assume he meant that maybe I am wrong.
Does anyone know their background how does sangwoo's father came to like taewon.
