A train moving through the twilight. Reflected in its windows are countless tired faces. One of them is mine, Kagurazaka Reiko.

Days just pass by as I do my office work at the company. Before I knew it, my peers had all left to get married, and now the new girls call me "old hag". Even though there are other women older than me, for some reason, it's just me... meanwhile male colleagues call me a leftover, and my stress keeps building up.

Then one day, a strange relationship suddenly began. Every time I get on the commuter train, there's someone who gropes me...

I hate it, really hate it, but no matter what... I just can't get off that train.

And so today, once again, I board the same train car...
