Plot
High school student Hanabi Yasuraoka has been in love with her older childhood friend who is now her homeroom teacher Narumi Kanai. But from the look in Narumi's eyes when he sees the new music teacher Akane Minagawa, Hanabi realizes that he is in love with Akane and not her. Hanabi meets Mugi Awaya, another student who is in love with Akane, who was his tutor when he was in middle school. Hanabi and Mugi make a pact and begin a fake relationship to satisfy each other's loneliness from their respective unrequited loves, both sexually and emotionally. They agree to not fall in love with each other and end the relationship if their love is returned from the people they are in love with.
