SDAB-221 ● Year ● Seri Mitsuha of the group is very interested in Iku and decided to consult with a boy who is a playhood friend.

During breaks, a girl in her class is having sex with her college boyfriend. A story that is too stimulating for Mitsuha. What is "Iku"? Mitsuha is thrilled and masturbates in the bathroom during lunch break. Takashi, a childhood friend who passes by in the corridor. My house is in the neighborhood and I'm from kindergarten. I talked to him with all my might, "Are you planning to go after school today? Can I go to Takashi's house?"
