bk is gay and go-gyeom being kind to him, probably there's a feeling at first but then gogyeom keep on sleeping with women which make bk numb. So bk is just bear with the relationship now as gogyeom promised to take him to seoul. Go-gyeom is also the one who often help bk, it's like bk is dependant on go-gyeom and go-gyeom took advantage of it
so basically gyeom ( the leech ) has know. baekhee( ml) since they were kids so hes also the only one that knows about baekhees past( his dad) back when they where younger gyeom promised baekhee (and still does) that once they graduate he’ll take him to seoul and makes sure the dad won’t find them. baekhee never saw any other option and doesn’t have the money to leave town by himself and since he’s so afraid of his father finding him, he views gyeom as a savior. he’s always trying to get on gyeoms good side that’s why he just lets him do whatever he wants. + he fears that he gets bored of him and won’t take him to seoul if he’s not a good boy lol. also he has said before that their relationship goes beyond mutual interest aka love.. he doesn’t like him romantically and doesn’t care much about the sex either he does it because gyeom wants it! it’s consensual so not rape but he’s not enjoying it (︶︿︶) only ilwoo deserves his love!! praying he’ll be endgame
also i think baekhee might me mistaking their situation and relationship as ,,liking each other“ i think he doesn’t actually know what it’s like to „like“ someone naturally without conditions and because he’s never been close to anyone else before and gyeom pushes himself onto him so much sexually he’s probably thinking that’s just what it’s like to have sex ╥﹏╥ but that’s just how i see it! maybe he’s fully aware that it’s not really normal but he does like him! just i don’t think it’s romantic
Obviously there's a time where 'like' grow but do to the circumstances, and how stressful their dynamic is it died quickly with gyeom still attached. Lowkey they have potential if only gyeom is not a cheating bastard.
And what makes me think like this though I do believe (it's just codependency) is their both each other's sexual awakening. – though I'm glad that the "sign" is subtle as this manhwa make sure it's not love triangle.
so baekhee and gogyeom were already super tight, but then their relationship became ambiguous after they started having sex, gogyeom might be conflicted about his sexuality or he might just be bisexual but he has a cheater mindset where he’s sexually available to anyone (girls in his case) but wants his partner to be tied to him exclusively

so he's obv not fine? if someone understood the dynamics between ml and that annoying leech sticking to him, can they explain rq? kinda forgot mb
