kaeya's left butt cheek's feed

i have to admit, even tho this webtoon has a very dark topic it was written very well. it's just a shame, bcs i know he's gonna end up with narye again, since chaehon is basically him just repackaged since he knew he can't do it the old fashion way so he manipulated the mc. and they guy who kidnap him is probably narye's brother from before too. like, it's written well but what's the fucking point when the author just gonna make him end up being with his abuser, rapist, and killer? i would only accept two endings: him escaping and be free of narye's clutch or him killing himself again. im so serious bcs no one would have been sane enough to be willingly get into a relationship with a lunatic like narye.

or, if chaehon is somehow not narye but i truly doubt that. what is wrong with people that write story like this? i genuinely want to know.
