Yuki Aoki/Relationships

Mizuha
Yuki has a crush on Mizuha and shows it very openly, even in front of her at one point, saying "A peaceful world is where your crush is in the club room.". It's unknown if she reciprocates his feelings, but she says that she likes someone who's in the same club as her. Given that Mizuha spends a lot of time with the Occult Club members, she probably likes someone from that club, which could be either Yuki or Hanna.
