Synopsis

A high school mystery, about anonymous letters expressing true feelings, being sent among students.

Kuwazuru Mitsuki is a second year student at Arakawa Nishi High School. As a rule of their class, every single student is required to write at least one anonymous letter per person to a classmate. At first, there are a lot of bad jokes and silly letters, but when the “bullying confession” letters start to circulate, it leads to more and more secret revelations and confessions, leading to the questions “who is the sender?” and “who will be named next?.” As the students begin to learn more about the “unknown” anxieties and concerns among their classmates, which until this point they had no interest in, the bond between them all gradually deepens.
Meanwhile Mitsuki attempts to determine the sender of the letter sent to her, and as a result she discovers a secret hidden within this “letter game.”
