when woojin realized hyung is cying as he does not want to have sex with him he stopped, when he heard mcs crush is disrespecting him he beat him, every time mc is cruel it hurts woojin. when they had the talk with big question "why are you doing this" woojin told him he hates that he hates him as since childhood he only wanted his brother attention. I don't feel he is the bad guy everyone thinks
according to the plot from the ch 1 it is stated that hypnosis is not working if he is repulsed by act, so woojin had to brainwash him step by step, however, through the story you are informed about his point of view and how hearth broken and hurt he was his whole life. he take care of his hyung, trying to protect him in his own way, he feels like shit while seeing him in pain... try to see this from different perspective with empathy toward both characters
Why do I feel like woojin has hypnotised the other dude and like right when mc thinks he’s getting his happy ending woojin gonna come in like “fwop fwop you thought” and SA mc yet again but mc will be hypnotised and “enjoying it” then he’ll wake up and not know why his asshole is loose and burning like wtaf (╬ ̄皿 ̄)凸
