I think is not as difficult, I believe that the "I win" of sangwoo is him winning against the uncle and the idea of anyone meaning or having an impact on Bum's life but him, making Bum so attached to him that no-one can be able to turn him against him, (as the police dude tried to do). So, him being nice with Bum is Him making sure Bum remains loyal to him, and more dependent of him than never before. (This without mentioning that it's possible that Sangwoo has indeed feelings towards Bum) ... But I could be totally wrong. ┑(￣Д ￣)┍
or he wins against the uncle. Maybe even both.
Can someone who can make sense of Sangwoo's intention pls explain to me? I've always thought I am good at understanding emotional connections, no matter how twisted or dark it is. But I am quite confused about what Sangwoo is trying to do. I thought about manipulation and superiority, but apparently more complicated about that.
One way to think about that "I win", could it be that Sangwoo is denying his affection towards Bum, like he is the winner in this relationship because Bum can do a blow job for him, while he couldn't. It makes him feel safe and proud that Bum is still dependent and inferior to him.
But there is apparently much more emotions in their relationships. Sangwoo is certainly transforming Bum into his own kind, no matter intentionally or repulsively.
Anyway, this chapter kinda freaks me out. If you have any clue about this, welcome to share with me.
