Izumi was born in a family of celebrities. His father is a singer, his mother an artist, his older brother the lead vocalist for the popular band CRUSHERZ. Izumi himself, however, is just a nerdy college student. He loves the manga "Magical Girl Lala Lulu" and dreams of becoming a manga writer himself. One day he is roped into filming a commercial where he wears a dress. Another actor on the set, Ryōma Ichijō, mistakes him for a woman and falls in love at first sight. As it turns out, though, they met ten years in the past. And Ryōma's feelings don't change when he finds out Izumi is a boy.
