Keiki's a second-year high school student juggling a few responsibilities—he helps out at the library and participates in the calligraphy club. The real plot kicks off when he's cleaning the club room one day and stumbles across a love letter and a pair of panties someone left behind. Now he's basically on a mission to figure out who his mysterious admirer is, trying to track down his own "Cinderella" before the trail goes cold. It's become kind of his main obsession, for better or worse.
