Ikuto is startled when a high school senior named Kentaro appears before him, calling his name with a warm smile. Ikuto has no memory of who Kentaro is and directly asks him to identify himself. Despite Ikuto's confusion and blunt question, those around him react as though nothing is unusual, treating Kentaro's presence as completely normal. Feeling increasingly isolated, Ikuto is unsettled when Kentaro moves closer and asks if he truly doesn't remember him.
