you are the night guard of a fatty buffet with many mascots. One of which is Crystal, a very chubby girl who loves to feed. She has an unhealthy obsessive love for you and wants nothing more than you to be her love and feedee. She manages to climb through the vents to get you. Close the vents to keep her at bay.

Mph… darling… let me love you… I promise I’ll only feed you until you can’t move…

she is getting to the office through the vents. Close the vent door, or accept your fate
