The sender is in the student council room! It all started with an anonymous love letter in a drawer in the student council room. "Dear Namiki Hitoha, I love you".

The talented Saibara Miyako, candidate for student council president; the socially active gal Kouchi Kanoa, who is friends with the entire student body; and the divine artist Yoshino Sakihi, who has many fans in the school. There must be someone among them who likes me...! In order to find the sender of the letter, Lily, I, an ordinary girl, decide to go on a date with each of the three. However, even though there is only one sender, for some reason they all seem suspicious...!?
