[Reducing Mosaic]JUR-366 I heard that our swim team is going to 'become a mixed-bath hot spring,' so I decided to join──.

"Today it's just the two of us... a private lesson, huh." I transferred to this school midway through the semester. It was mandatory to join a club, and I was hesitant, but I was invited by my homeroom teacher and swimming club advisor, Mr. Kimura, to come and observe at the indoor pool. And then, I was shocked. The club members weren't doing freestyle or breaststroke in the pool. One student was drinking coffee milk, someone was washing their body, and there were even students who were "all tidied up"!? There were even guys getting cozy with female club members??? What is this place? A mixed bath hot spring!? However, I decided to join this swimming club.
