I'm lost hellp

I forgot which chapter they started breaking up cuz I low-key dropped ts last year but I specifically remember that one chapter where the blond dude finds out that black dude was using him as a reference to his bl story shenanigans which caused a misunderstanding as blond dude assumed that black dude was low-key using him and blond dude gets mad and triggered because of his past trauma or whatever. Can someone tell which chapter that is? Arigatonyan.
