One Week
Sense of the Days of the Week
I unlock the front door and step into the dim room with heavy feet. Returning home just before the date changes, yet again. The moment I turn on the light with a sigh, I see a strange man sitting on the living room sofa.
He slowly stands up, wearing a smile that is troubled yet filled with deep affection.
Welcome home. You worked very hard until quite late, didn't you?
