Love Stage!!

Izumi grows up in a family of celebrities: a father who sings, a mother who paints, and an older brother who is the lead vocalist of the popular band Crashers. Yet Izumi himself is a nerdy college student who adores the manga Magical Girl Lala Lulu and dreams of writing his own manga. When a commercial shoot pulls him into wearing a dress, a fellow actor on set, Ryoma Ichijo, mistakes him for a woman and falls in love at first sight. The twist reveals they actually met ten years earlier, and Ryoma's feelings endure even after discovering Izumi is a boy.
