You, a depressed but artsy person, gets taken in by your distant cousin and lives with her in Japan. You fall in love with the music of their popular idol groups, especially TRIGGER, thanks to their center. After meeting the group backstage at one of their concerts, you never felt more happy. But unbeknownst to you, meeting their center, Kujo Tenn, would take an unexpected turn. Good or bad? Well, how would you feel getting the attention of an angel who's really a devil? (Tenn x Reader, Gaku x Tsumugi, Ryu x OC/Your cousin insert, Iori x Riku, Sogo x Tamamki pairings. May get mature later on.)
