Earlier in the chapter when Nanjo calls Mokyeon an abuser, I think he is doing so not because he actually believes that, but more so that’s the only thing that’s keeping him from falling for Mokyeon. So that belief is grounding him in not going farther with Mokyeon, and also that Mok hasn’t kept his promise abt the twink. I think he has a whole complex with him, seeing him both as competition and a sexual partner. He feels jealous of his relationship with the twink, yet wants Mok to be a bad person so his feelings don’t deepen.
