As a college student, Saijou possesses the unique gift of perceiving a girl's love through sparkling imagery. However, since he fails to witness any such sparkles directed towards him, he refrains from interacting with girls other than his middle school pal, Kitashiro. That is until one day he encounters Shinonome, a curious girl seeking to understand the concept of love, leading Saijou to befriend her, seeing a resemblance between them both.
