Our “Simplistic” School Life.

Being average at an elite educational institute such as Kinijro Metropolitan High is quite a task by itself, but what if a bit of blackmail was added to the mix? Now you have a recipe for disaster baking slowly.
Yamaguri Yuki prefers to keep his head down, until he comes across one of the year group's beauties, Mashiro Saya, changing her clothes in the classroom.
Instead of screaming, Mashiro offers Yamaguri two ultimatums: become her fake boyfriend or be branded a peeping Tom by the school. Desperate to maintain his peaceful school life, Yamaguri accepts her proposal.
By doing so, Yamaguri unknowingly drags himself into a multitude of situations where his school life drastically changes.
