A middle-aged man trapped in a mundane life with no hobbies, estranged from his wife and daughter, had lost all hope. One day, on his way home from work, he collapsed after being tripped by his daughter. At that moment, his daughter's classmate, Sakura, looked at him with a curious gaze—her eyes shimmering with a strangely seductive light. Sakura was no ordinary girl; she was drawn to emotionally worn men, awakening intense sexual desire within them. From that day on, a sweet yet heartbreaking affair began between them.
