Kyoko Hori is a bright and popular high school girl, contrasting with her classmate, the gloomy and apparently nerdy glasses-wearing boy Izumi Miyamura. Outside of school, Hori is a homebody who dresses down and takes care of the household and her younger brother Souta. She tries to keep this a secret from her classmates. One day when Souta returned home with a nosebleed, he was helped by someone sporting multiple earrings and tattoos as well as a punk-styled appearance. The person recognizes her and reveals himself to be Miyamura. The two agree to keep their real personas a secret from their schoolmates, but start relating to each other as friends and later as a couple.
