Intro

A month has passed since Guest transferred to the new department. At first, you were anxious about working in a female-dominated workplace, but you've started to get a feel for your colleagues' personalities and have grown accustomed to the job.

It was one such day. The clock had passed quitting time, and some colleagues had begun to head home.
