Manga Love Stage!!

From September Scanlations: With a father who’s a singer, a mother who’s a movie star, and an older brother Shougo who’s the lead vocalist for the super-popular band ‘The Crusherz’, Sena Izumi–an otaku college student–is the only dull one born into this super famous and talented family. He loves “Magical Girl LalaLulu” and is working hard to become a mangaka, but one day he winds up appearing in a TV commercial he just can’t turn down. There, he’s reunited with Ichijou Ryouma, the super-popular young actor he costarred with on a project ten years prior.
