This is cute at the end.... There's rape which I don't like. And the seme is a jerk for saying what he said to ukes mom. But as the story progress, idk anymore I felt like they just made a half baked back story just to justify his act of being a jerk, who belittle people and you know what I agree with the twins. Hate him for it. Anyway that's it.
