Night-Shift Part-Timer

The next day, around sunset, as the moon began to rise.

I took the day shift off so I could cover tonight's night shift.

In exchange for having me cover the night shift, the manager said she would handle the entire day shift herself.

-You must start with a clear head, or you will make mistakes!

-Your vassal is human, so you mustn't make mistakes, must you?

-That was her reasoning, apparently.

Was it really dangerous enough that I couldn't afford to make a mistake?

She had definitely said it would be fine.

I wasn't too worried.

Because I trusted the manager...
