Reika's relationship deteriorated due to her husband being laid off, and she started working part-time because she couldn't make ends meet. She had a hard time getting used to work because she had been a housewife until now, but a young man named Jin, who is younger than her, gradually brought them closer together...One day, they held a welcome party. When Reika opens it, Jin invites her for a drink. Reika, who suffers from permanent stiff shoulders, is good at massaging.
