Maaya Kisaragi, 16 years old, finally confessed to her crush…only to be flatly rejected and ridiculed on social media after. To make matters worse, the most popular guy in her grade, Chigira-kun, overheard her despondent muttering about the whole thing. But instead of making fun of her, he comforts her…and proposes an odd solution to her heartbreak!
“I can do my best because I wanna be with Chigira-kun,” thinks Maaya, who’s become a third-year student. Surprisingly, she ends up participating in the sports day’s key event—the relay race. Maaya’s at a loss since she can’t lean on the busy Chigira-kun as the event nears. However, her classmate, Azumin, volunteers to coach her. Just what is Azumin aiming to do by suddenly getting close to her like that?!
