Returning home for the Obon holiday after several years away in Tokyo for university, Souta felt a sense of comfort at the unchanging scenery of his hometown, his first visit in three years. However, the person he encountered upon returning home was his older sister, Claire, a woman in her late twenties, still wearing her high school class T-shirt and living in a messy room. Having divorced while Souta was in Tokyo, she had become a lonely, unattractive woman who spent her days watching BL (Boys' Love) anime.
