I think it's like sangwoo think he can he can do anything what he want to do like no one is above him like get any girl kill any person..even now in this chapter he always make bum to do things what he likes..but when bums making a move he wisely refused him..so it's look like sangwoo never do things of others will..
Pretty sure it’s about Sangwoo’s father, throughout this whole thing he freaks out about not wanting to be his father, who beat his mother and treated her like shit, and when he has nightmares or hallucinations his mother would say he’s just like his father. He “wins” because he is treating Yoonbum nicely and has made him happy, and since bum reminds him of his mother, he’s treating his “mother” better than his father did, therefore winning over the bad thoughts of becoming just like his father
This is really good point of view..
whats the meaning of "I WIN"? woow koogi seriously knows how to stir up readers minds!!!man every week something to wonder about!!i will never understand till the end what sangwoo is plotting!!i see no red light yet!!!and one thing for sure he's not very fond of having sex with Bum(hes not gay after all)as the same as bum tries to be beside with sangwoo,sangwoo is doing the same thing(having sex) with bum to make him stay with him i guess...but wonde why,because he doesnt even love him or something...
