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.
Mizuki disguises herself as a boy and transfers to the same all-boys' high school her idol, Izumi Sano, a high-jump athlete who gave up on the sport, attends. In between their classmates' antics she tries to get him to jump again.
Mob tries to avoid being the main character in a BL world, but as love finds him, he must choose between staying in the background or embracing romance.
