Izumi Tomohiro was appointed student council president by drawing lots. At first, he carries out his duties adequately and without risk, but before he knows it, he begins to feel a commonplace sense of commitment. He becomes so active that he even goes out on his days off with the other members.

One day, Tomohiro is forced to participate in a doujinshi sale as a staff member of a kojin circle. After selling the books, he leaves his seat to buy a drink. On the way, he wanders into the original creation space on a whim, and spots someone who shouldn't be there...

This is the story of a girl who is not the main heroine, and who strayed out ("hamidashi") from the main story.
