Eiji has a recurring problem: every woman he dates dumps him within a month, always with the same reason—he's too boring. After his latest breakup, his younger brother's friend, Kou, boldly declares that Eiji should go out with him instead, claiming he can prove that Eiji isn't boring at all.

Easily led by the confident Kou, Eiji finds himself drawn into an unexpected relationship. As Kou's persistent attention challenges his self-image, Eiji begins to see himself differently—and can't stop watching the boy who turned his world upside down.
