Wataru Sajou is infamous in his school for persistently seeking the attention of his crush, Aika Natsukawa. His usual day revolves around shadowing her and confessing his undying love at every turn.

He distances himself from Aika and spends his newfound spare time with his friends and in the company of other lovely girls.

As Wataru moves on, Aika starts approaching him in unusually suggestive ways—making him question whether giving up on his love was the right decision after all.
