1. First one is about a girl who starts working at some guys place as a housekeeper/maid and discovers a secret room filled with plushy toys - bunnies. He likes bunnies very much and when the girl discovers it she teases him a little bit about it. Sweet, funny shoujo manga.

2. Second one is about a woman who is an art teacher. She meets a very cute guy who admires her work, and she wants to bully him to see his crying face because she thinks he's sweet and cute, so she steps on the painting he drew. Im not sure but i think in the end they had sex

If you know any of these mangas, help me! Also could you reccomend me a manga where main character or his partner likes to bully his crush or has a split personality like in Ikenai Candy Love or Junketsu Drop?

I think number one is part of Akuma de Koibito, the one shot named That's the Rabbit's Forest, the first one shot after the main story
