Salaryman Kashiwagi runs into Kurasawa, a high school classmate, in the middle of town. Kurasawa, who was once modest and mature, had turned into a very beautiful man. Although very put back by the sudden change, Kashiwagi decides to visit the bar where Kurasawa currently works and he’s surprised yet again by the cool and collected way he tends to the customers. However, the way Kurasawa only acts stubborn in front of Kashiwagi and gives him passionate looks just like old times, makes Kashiwagi feel comfortable. An unpredictable reunion love.
