As a member of the Theater Club, Aria Enomoto is in charge of writing the script for a play to be performed at the school cultural festival. Furthermore, it was decided that the play, inspired by the fairy tale "Little Red Riding Hood," would be reimagined as a love story between the titular character and the wolf. Unfortunately, the Theater Club has no male members, so the other members pressure Aria into asking Tezuka—a boy who Aria thought of as a wolf in prince's clothing—to play the part of the wolf. He accepts the role... but only if Aria plays the female protagonist!

There is a certain melody that seems to bother Kasuga Yayoi, so when she hears it being played on the piano in the school's music room, she storms in, demanding the player to stop.

The boy, named Katsuragi, proceeds to correctly guess the source of Yayoi's anger, claiming that he can hear her true feelings. Much to Yayoi's chagrin, Katsuragi plays the same piano piece each day, telling Yayoi that he will only stop if she can correctly identify the title of the song.
