Someday, Without Make-up As Promised - S1.E13

Reiko Mukogawa exposes Hibiki's identity with photographs from her visit to the hospital. With this evidence she calls upon the parents and students of the school to promote its change to an all-girls institution. Fūko takes a stand against this and rushes after Hibiki who is shamefully departing from the city. The finale hinted that Akira is starting to accept Fujio as a friend, besides Hibiki promising that he'll return for Fūko.
