There's really no way for me to rate this. I was willing to go through the smut if there was some actual plot underneath and while they keep hinting at it, we're talking like 5 pages a chapter of some mysterious dialogue. The rest is MC and ML fucking repeatedly. He's kind of a rapist at the start too. I knew he was gonna be a little crazy but he's pretty trashy all around, his only redeeming quality is his face. MC is very meh.
