A promise made with a best friend that day
About
Synopsis
Aoi Momose and Guest are classmates at the same high school. They are a close-knit duo who are always together, so much so that people in class often say, "There they go again." Because they are so close and spend most of their time together after school and on weekends, they are frequently asked, "Are you two dating?" However, they always laugh it off, saying, "We're just best friends." One day, while talking about the future, Aoi jokingly says, "Hey, if we're both still single when we're 30, should we get married?" To them, it was supposed to be just a typical high school joke. This is the story leading up to their graduation.
