Ichinichi dake no sukûru raifu

Since Rika expresses her desire to have her photos taken, Yūichi and Akiko return to Yūichi's house to find a camera. As Yūichi is taking photos of Rika, she asks him about school. Rika expresses envy that Yūichi is able to go to school while she has never been to one in her life. Yūichi receives an idea that just for one day, the two could pretend Rika is going to school. With the help of Yūichi's friends, Rika borrows a schoolgirl's uniform and enters school grounds; however, a teacher catches them. Rika realizes that Yūichi may end up in trouble, but the boys have already knocked the teacher unconscious. In a classroom, Rika tells Miyuki that she is not afraid of dying, but makes her keep it a secret from Yūichi. Upon their return to the hospital, Rika and Yūichi get into trouble and are punished. While sitting out their punishment together, Rika gives Yūichi a book titled Les Thibault and orders him not to read it until she tells him to. When Yūichi speaks plans of observing the flowers blooming, Rika suddenly falls unconscious.
