Shuuichi likes Wakaba. Wakaba likes Shuuichi. When the time finally comes to Shuuichi to confess how he feels, they’re busted by their guidance counselor for breaking curfew. Shuuich and his friend are told to write essays that reflect on their actions while Wakaba and her friend are taken by the hard-ass teacher for some “guidance”…

Day two of the trip begins. Without a breath of what happened last night, the group heads to the aquarium. Finding themselves all lone, Shuuichi confesses his love for Wakaba and asks her out. She says yes, and that night, they agree to meet up, have sex, and be gone before the counselors make their rounds. But what the boys don't know, won't hurt them…

Wakaba and Maika are back from the group trip with their classmates. So far, Mr. Nashida hasn't said a thing to them, so the two appear to be in the clear. That is, until one day when Wakaba walks by Mr. Nashida's office and sees that Maika is still having sex with him! Dissatisfied with her boyfriend's dick, is this Wakaba's only path forward?
