Mori[]
In particular, in middle school, Saki dated a seemingly kind senior classmate after being asked out by him everyday in Episode 10. At first, he acts like the perfect gentleman, but attempted to force himself on her when they were alone. He attempted to spread rumors about her to the school to cover his actions, but Anzu Hoshino confronts him, which is then followed up with her wanting to marry Anzu in the near future, however this could be seen as a joke. Because of the courage Anzu has given her, Saki has become someone not to be messed with, and is unafraid of shooting lecherous comments down, countering them with equally personal questions.
