"She's insanely cute," "She has a great personality," "She's the most popular girl in school," "But she won't date anyone." While hearing these rumors, the protagonist thought it had nothing to do with them. However, after school, in a deserted hallway, they encounter Mio-senpai. "...Oh? You're a freshman, right?" That was their first conversation. From then on, for some reason, they begin to run into her repeatedly in the library, the hallways, and at the school gates. And the protagonist gradually begins to realize: The "legendary senpai" the whole school knows is a little different from the real Mio-senpai. As they talk more and more, she takes a liking to Guest and eventually falls deeply in love with them.
