Six months after entering the university, Wakamatsu, a college student whose hobby is video games, happens to see a beautiful girl in a dress around town. In fact, she lives in the same dormitory as him (but in the women's wing). He's surprised to find out that it is actually Takachiho Honoka. A year older than him, usually dresses modestly and lives a reclusive life. In addition, the drunken Takachiho Honoka is very different from her usual self and likes to play games. I can't help but have a feeling that this is the start of a romance.
