Slavery absolutely did not end because it was unprofitable. The very notion is ridiculous. America had a big war about it specifically because entire economies depended on it.
I'm a little concerned about how accepting he is of slavery. Not expecting him to do anything about the institution...
He's not gay, she's annoying. Dudes are allowed to not like individual women. Violating privacy, sexual harassment (dropping the key in between her breasts counts), lying about their relationship in front of the student body in order to embarrass him. I'd want nothing to do with her either.
Yeah, she's an athlete, but she's also still in school. She spends most of her day sitting at a desk. 5000 kcal is waaay too much. Her problem with her diets is she cuts too much and can't handle it mentally. I lost weight by cutting calories, and the hardest part is just living with the hunger.
When did Rudeus lose his memories of her? He has all his other memories from before the incident. I thought her sunglasses were magic that, among other things, blocked him from recognizing her?
I'll blackmail you with this picture of your dick that when anyone asks "Why do you have that? Isn't that technically child porn?" I'll have no answer!
Is this real? Yes, gay people are born gay. Bi people too. Hentai isn't real, no one takes the rape happily. You can't change a person's sexuality by raping them. There is no external trigger to turn a person gay, bi, or straight.
