Strawberry panties set against a sunset sky—that was how aspiring film director Junpei Manaka first encountered a mysterious beauty in middle school. Suspecting the girl is his classmate Aya Toujou, Junpei attempts to contact her to reshoot that skirt flip for "artistic" reasons. However, when he runs into her the next day, he sees a girl who looks vastly different from the one in his memories. Just as Junpei thinks he is back to square one, he encounters the school's darling, Tsukasa Nishino, who boldly declares that she is wearing strawberry panties for the day. Convinced that Tsukasa is the girl he has been searching for, Junpei begins planning his confession—all to become her boyfriend and film her panties!
