Don't know why everyone thinks this is a messed up chapter. Seungeon is actually helping Jiwook in this chapter. First, he asked him if he was okay and asked permisssion for everything he was doing. Seungeon put Jiwook in the dominant position to give him control, asking him to scratch him, hit him and choke him to release that anger and resentment and put a stop to it if he can't go on. He could tell when Jiwook was in distress and reliving his trauma, he kept bringing Jiwook back in the present and reassuring him that he is giving consent and he's with someone he likes not those thugs. If you look at it that way, it's actually a beautiful chapter. Just my opinion.
