When I heard that my swimming club had been turned into a mixed bath hot spring, I decided to join.

"Today we're alone... it's a private lesson." I transferred to this school in the middle of the first semester. I was unsure about this place because it was essential to join the club, but I was invited by my homeroom teacher, Mr. Kimura, who is the swimming club's advisor, to visit the indoor pool. And I was shocked. The club members were in the pool and didn't crawl or breaststroke. One student drinks milk coffee, washes his body, and even has a "well-fit" student! ? Even the boys flirting with female members??? What is this? Mixed bathing hot springs! ? However, I decided to join this swimming club.
