Idol-sama ga Real Koi suru na

Fuma Kodaka is laser-focused on his acting roles to the point of ignoring anything that doesn't have to do with his career. So when this stubborn actor has trouble getting into character for his role in a new TV show, he feels lost. Luckily for him, he bumps into Kanade Suou, a super-popular prince-like idol. Kanade is strikingly similar to Fuma's next role, so in order to study Kanade's sweet and sparkly mannerisms, Fuma asks him out on a whim. Surprisingly, the handsome idol readily agrees without any hesitation!
