Kiriko Terada is self conscious and shy. Having grown up in the shadow of her beautiful, athletic and talented older sister Eiko, Kiriko has never stood apart or found love; she has styled her appearance and demeanor just like Eiko, in hopes she'd become just as popular and well-liked. However, after a lifetime of being ordinary Kiriko finally takes a stand at sixteen-years-old, when she finds out that her sister is her new teacher and is dating a student - a student who wants Kiriko to pretend they are dating to protect Eiko's job. Cutting her hair short and gaining a new friend named Ketsuka, Kiriko now moves forward as her own person - a person who will find and lose love, comedically fight off the advances of Takeshi the pervert, and see for the first time that her sister has her own set of flaws.
