One day, he meets Rika, a girl his age staying in the adjacent hospital building. Drawn to her striking presence and unique personality, Yuichi finds himself increasingly intrigued by this mysterious girl who seems to live by her own rules. As their paths continue to cross, an unexpected connection begins to form between the two patients, each carrying their own private burdens within the hospital walls.
