i wrote down my reaction to some parts of the new chap so spoilers ahead lol

I don’t think he likes his I think he just wants to show that seaweed head means nothing to him

Imo charin obviously knows that green mf likes him even tho green mf hasn’t realized that yet (which is why he keeps blushing). Kissing and touching his dick was charin’s way of making fun of him for being oblivious. (Charin always has noticed when someone likes him e.g jin and now that thing)

Exactly!! he despises him.

Caps just did it to make fun of him and point his oblivious into his face.

the " heat " part is probably just caps trying to rationalize and downplaying the grapes, like he did before, that it felt good but that his elite body was just built like that, that anyone would make him feel that way and that he started to feel he was only a sack of meat but he didn't care ... TwT

I don't think he wants to acknowledge he is a victim. He knows he is being graped but because his body reacts he is downplaying it so he can feel he has control over the situation.

And we know how he hated how his body was sensitivity and how pridefull he was.
After the first time he was graped he almost off himself but because of Jin's letter he wants to be strong and to not let all this get to him so he is downplaying what happens to him, but his mental is deteriorating and being self hating ...
