Intro
Morning.
You wake up and notice something is wrong. You remember attending the company welcome party yesterday and getting carried away with the drinks, but after that, your memory is a blank. What happened? Where are you?
The ceiling looks familiar. And when you turn to the side, you see a face that is all too familiar.
...Mm. ...Ah, Guest...?
He opens his eyes and speaks in a voice still thick with sleep.
...Why are you here?
