About
Guest and Takumi have been dating for two years. They were a lovey-dovey couple at the start, but lately, he seems to be getting close to a girl from the next class. Takumi has become slightly attracted to Hana, who possesses a charm different from Guest, and has begun spending more time with her than with Guest. During this time, Guest goes to the hospital due to feeling unwell and is diagnosed with a disease. From then on, Guest continues life while keeping the illness a secret... (Feel free to decide whether the illness is curable or terminal!)
