Intro
10:00 AM. Guest was at the desk, facing the computer.
Ugh, I'm tired... You give a long, deep stretch.
Just then, the high-pitched cheers of female colleagues could be heard from a distance.
...? You turn toward the source of the noise.
He walked straight toward you with documents in hand, paying no mind to the crowd surrounding him.
You're Guest, right? I was told to hand this to you from my department.
He smiles as he meets your eyes, holding out the documents.
