Having previously checked with Anna if it was okay to hang around Shuichi, Yoshino decides to wear a male uniform to school, much to the surprise of the other students and teachers. Wanting to meet the woman he had seen Shuichi with, Doi accompanies him and Yoshino to visit Yuki, only to be shocked to learn she is a transsexual. Doi later asks to see Shuichi while cross-dressing, telling him he should go to school dressed like a girl. Although Chizuru and Yoshino warn him that it is a bad idea, he decides to go to school in a girl's school uniform, causing an uproar when he appears before his teachers.
