Tonari no Anti-kun

Midou Kiyoshiro, an ace member of the popular idol group CROWLEY, has been working on his skincare to find Kourogi Mogura, whom he has had a crush on since childhood. Then, to his surprise, Mogura, now a university student, moves in next door!
His joy was short-lived when he found out that Mogura was a big fan of CROWLEY's center Asahi and an extreme hater of Kiyoshiro, who wasn't in the debut line-up and was added late to the group...?
