High-school student Akari has only one passion in her life: her oshi, her idol. His name is Masaki Ueno, best known as one-fifth of Japanese pop group Maza Maza. Akari’s dedication to her oshi consumes her days completely. She keeps a blog entirely devoted to him, religiously chronicling and analysing all his events. He is the spine of her life; she cannot survive without him. When Masaki is rumoured to have assaulted a female fan, facing waves of social media backlash, Akari’s world falls apart.
