Youth only comes once in a lifetime. It’s the time to go out and play with friends, do your best to achieve your dreams, and fall in love. Yuu is a second-year student at Ishigami Gakuen who is wasting his youth away. He thinks that he should do something about it, but lacks the motivation to take the first step. He soon meets four girls who have their own worries: Ai, the school’s #1 beauty who calls herself a delinquent; Akane, his classmate who yearns for the spotlight; Shiori, a quiet girl who is looking for ghosts; and Kana, his osananajimi who wants to get along with her friends once more. He spends precious time with each of them in turn.
