Many things of this manhwa doesn´t make sense, it's just to make it more interesting or different from other stories (i guess), so somehow they're going to end up together, even though of course is damn annoying （/TДT)/ (╯°Д °)╯╧╧
This isn’t a fluffy story , both taekjoo and zhenya are both morally grey characters. It takes a lot of development and events taking place for taekjoo to actually see zhenya romantically, it doesn’t just happen quickly. The thing about zhenya puttin taekjoo in isolation was actually for taekjoos own good and it will be revealed why however that’s not me defending it
This manhwa is so fucked up that I don't even know how the author will make them lovey dovey when all they do is hurt eachother and zhenya raping taekjoo and put him into isolation ╮(￣▽￣)╭ (and yeah, I haven't read the novel)
