There is a lot of sex throughout, but all of it is rape. It never becomes something the uke is okay with and the whole time he is forced to do it. Gets worse when dorn president starts letting groups of boys from the dorm rape the uke at the same time. Honestly, not as psychological as it could have been because the Uke actually enjoys it when he is paired with the Seme even though it is never consensual. The uke x seme relationship is abusive and you keep wanting it to turn into something tender and for the uke to finally find relief, but that doesn't happen. The seme just keeps fucking the uke up mentally, socially, and physically.

It bothers me that this is labeled by some as somnophilia, he doesn't have a syndrome where he is aroused due to his friend's unconsciousness. He is just aroused by his friend and takes advantage of his unconsciousness.

This is such a moral turn off. But this author does make the sexiest, hottest scenes. Even the ones twisted as fuck like this.

So the teacher is nice and lovely. He does sexual stuff with the uke but not full penetration because the uke is a minor. But the one is constantly bullied at school and assaulted sexually by his uncle (being physically interested and raped respectively). This teacher who cares about him tries to help but also cares and becomes possessive?
