Mimibu's manga / #teacher x student(2)

Low 4. Kinda hot. Poor story development.

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?
