Nariyuki Yuiga comes from an impoverished family, so he's eager to secure a full scholarship to college before he graduates high school. His principal agrees, with one stipulation--he must tutor three of the most talented girls at school and make sure they get into their target colleges!

It's time for the school festival, and that means delicious food, amazing performances and beautiful cosplay! But wait--why is Mafuyu Kirisu wearing a costume too? Isn't she a teacher? And did Fumino Furuhashi really kiss someone as part of a play?! This year's festival is going to teach everyone some risqué lesson in love!
