The preview video starts with the main character, Nobuko, being asked, "Mobuko?" She has always been looking from afar at a world where other "protagonists" other than herself shine, but when she meets Irie, a young man with a "heart," at her part-time job at Super Tokumaru, she gradually becomes attracted to him.
