A man trapped in an endless sterile subway passageway sets out to find Exit 8. The rules of his quest are simple: do not overlook anything out of the ordinary. If you discover an anomaly, turn back immediately. If you don’t, carry on. Then leave from Exit 8. But even a single oversight will send him back to the beginning. Will he ever reach his goal and escape this infinite corridor?

Diagnosed with dementia, Yuriko's mind quickly begins to fade. Yet, for her son Izumi, memories of the mother feel as vivid as when he lived them. One in particular, when he believed she had disappeared, haunts him terribly.

This story is about the various possibilities in life faced by a mother and her son. They arrive at a train station in a small rural town with some purpose in mind. On their way to their destination, the parent and child are faced with a variety of choices. While some of the choices are trivial, others are very important for the two.
