Strawberry panties backdropped against a sunset sky—that was aspiring film director Junpei Manaka's introduction to a mysterious beauty at his middle school. Suspecting the girl is his classmate Aya Toujou, Junpei sets out to get in touch with her to refilm that skirt flip for "artistic" reasons. However, when he bumps into her the next day, he sees a girl that looks vastly different from the one in his memories.

Just when Junpei thinks he is back to the drawing board, he runs into the school's darling, Tsukasa Nishino, boldly declaring that she is wearing strawberry panties for the day. Convincing himself that Tsukasa is the girl he has been looking for all along, Junpei starts planning his confession—all for the sake of becoming her boyfriend and filming her panties!
