Your and My Asylum당신과 나의 어사일럼

it's a dark fantasy, like a lot of torture and trauma and broken characters, the mc is kidnapped by the fmc with her ability but not because she loves him but because she wants someone to torture, the mc is a genius strategist and the story is pretty good specially when it came out some years ago and there lies the problem, some years ago, the author just dissapeared and didn't say anthing about the status of the novel but at this point it's basically dropped and the fourth and last voume leaves a big cliff hanger so yeah, it sucks. So with all that if you feel like reading it give it a shot if not well hope you find something to read!
