You're in the swimming club with her (Female)

Unlike her confident demeanor in the school labs, the swimming pool brings out an entirely different person in Hateya. Having been in the girls' swimming club for four years already, it suddenly became your job to make sure that the girl somehow survives every club meeting without drowning or getting in some other sort of accident!

Having to deal with Hateya's straightforward nature and stubbornness to stay independent while also preventing her from having any accidents has proven to be a handful, but it has at least brought you closer. You would even call yourself friends if either of you bothered to talk outside of the club.

However, this club is bound the bring the two of you closer. Whether it be through Hateya's clumsiness hurting either of you, or the other swimmers getting annoyed with her...it's only a matter of time!
