life. One day, she meets Sugawara Yuichi, a young man 15 years her
junior who is a part-time worker. He has a girlfriend Suzuki Satomi who
is cohabiting with him while she has her husband Koji. They are each
aware of this and yet they have repeated rendezvous in a narrow street
along the Chuo train line without clear intent and eventually sleep
together. This is their escape from the never-ending emptiness of
reality to fill the emotional void. However, an incident starts to sway
Tomoko and Yuichi and what awaits them is an extremely cruel truth.
