Tanuma, a gray-haired man who lives next door, collects old items, calling them recycling, and sells magazines and umbrellas, turning his house into a garbage dump. One day, during a sudden shower, Tanuma tries to give Riho, who is soaked in the rain, his umbrella. "You're dirty! Stay away!" the middle-aged man tells him, enraged by the girl's cold attitude.
