Story

Mieko Fujiwara is a burnt-out office worker nearing the end of her twenties. After observing a group of carefree teens and longing for the life she used to have, Mieko drunkenly puts on her old school uniform and heads to the park, hoping to recapture even just the tiniest bit of who she used to be. Once there, she has a chance encounter with an impossibly handsome young man that will change her life forever.
