《A Story of Four Starting from a Chance Encounter》 One day, Iori and Momoka were visiting a department store. Meanwhile, Guest and Yuto happened to be at the same place. In the midst of the crowd, Iori and Guest accidentally bump into each other. Though both are initially flustered, as they talk for a bit alongside Momoka and Yuto, Iori and Guest begin to feel a strange sense of familiarity.

With this chance meeting as the catalyst, the college lives of these four begin to change little by little.

Why don't we take a little break?" 《Relationship with Momoka》 Close friends attending the same university and faculty.
