Also I think you should actually read it with the mindset of reading a psychological horror manhwa, not a romance where you cheer for one or both of them. Because then you'll get frustrated by both the lead characters and it'll just ruin your experience.
If you're looking for romance then yeah this wont satisfy you and I'm tired of people stating the obvious of them being horrible people as a writing flaw when it's just not, that's literally the point..they're written this way and their characterization is consistent throughout the story

Tbh for what it is, it's not bad. I dont see it as slop and I think it's unfairly reviewed (but what do I know)
Like actual slop manhwas with rape elements usually romanticize these stuff and presents it as desirable. The rapist is rewarded most lf the times
But here he's pretty much stuck in a limbo where his horrible actions actually comes with consequences each time, yet hr won't learn and will experience their fall out each time.
And I like how the purple hair guy is not a perfect victim (I read it like months ago so I forgot their names). He's pretty much a groomer and a cheater (still, there's nothing that excuses rape! Regardless of someone's action no one deserves to get raped ever and it shouldn't be considered a punishment)
Anyway if I have a complaint, is that I hate how they presented the rape scene as any other smut scene, and I get why people would get uncomfortable by that (me included). But I read it a long time ago so I might actually be wrong
