sereia's Questions (3)

Help me find! Based on a novel I think. The female mc comes from a proper Japanese household, but is mistreated while her sister (half sister?) gets all the favor. The family arrange for her sister to marry her childhood friend, one of the few people who has ever treated the mc well, while the mc is engaged to someone known for having a bad temper. Her fiance ignores her and expects her to break off the engagement, but she dutifully accepts her role essentially as a housekeeper. The story follows their relationship getting closer.

There's a scene where she's bowing to him for a looong time without him acknowledging her, and a scene where she cooks him breakfast and he doesn't eat it.

Japanese yaoi - there was a high schooler that hung around older (maybe university) guys, always going to someone's apartment to play cards and drink. After one meetup he comes back to return an umbrella and sees two of the uni friends having sex through the window. I don't remember much about the story outside of this scene. I think the student develops a crush on the uke uni student.

Forgot to mark it and can't remember the name. There are spirits/possession and a central demon character named Yama. The world revolves around yin/yang energy, and goblins need to digest yang energy, which they can do with sex. Help link me?
