セブンデイズ

Toji Seryo is a first-year known for a strange habit: he will date whoever asks him out first on Monday, then end things after seven days. On a whim, jaded upperclassman Yuzuru Shino asks him out half as a joke, and Toji says yes. As the week runs down day by day, what started as an idle dare turns into real feeling, and Yuzuru begins to dread the Sunday when the arrangement is supposed to end.
