Koutarou Sano, an otaku and former social recluse, had his world opened up thanks to meeting the somewhat obscure idol, Kei Miyamoto. Just as he is thinking about Kei, who has retired from show business, he runs into him by chance at a beef bowl shop! Flustered, Sano is then hit with an outrageous request from Kei...?! A "happiest-in-the-world" dream life, sparked by a reunion with his former "fave," begins now!
