Mizuki Sakura, Midorikawa Akane, and Momozono Yuriko are new teachers! They get flustered during a substitute sex education class, try out a swimsuit episode at the school pool during the hot summer, and sometimes, like proper teachers, they are adored by their students who even form a fan club for them... This is the third volume of a laid-back and relaxed girls' comedy about teachers who are doing their best to live their lives!
