The uke did do something to deserve this, he just doesn't remember so it hasn't been shown but it's hinted at. Juyeons life was basically ruined by jiwook, so he won't come to his senses everything he's done is irreversible. It'd be more realistic for them to stay together and keep hurting each other or for one of them to die while the other is left completely broken not out of love or mourning but probably mental illness. But jiwook did do something to prompt this situation hence the alternative title being "walk in my shoes"
Okay but what could've he possibly done to get such an extreme punishment like this? It would be bit more understandable if it's got something to do with -I'm assuming the woman in the hospital is semes mother- his mothers health issues, but if it's for something like a high school bully revenge then that'd be unforgivable.

I'm actually so close to dropping this manhwa this is too fucking much the only thing keeping me is the hope i have for uke to just be fucking happy for ONCE, the poor baby is just getting r*ped, manipulated, blackmailed, and humiliated every chapter this is not enjoyable at all, and don't y'all even think about trying to defend something here. I wish this manhwa would've gotten an actual good ending with either seme going to prison and uke moving on with his life or one of them dies atp. But that's not what's gonna happen i believe, this toxic relationship is gonna drag on for long enough untill either the uke goes insane and accepts his fate with seme or seme actually coming to his senses, unfortunately it's gonna be either one of those because this stuff just sells better than an actual realistic ending. ┑( ̄Д  ̄)┍
