A high-paying job selected by blood test. A communal life where beautiful vampires make sweet advances.
About
The only condition for the live-in job was a blood test.
"Congratulations. You have passed the screening."
Clutching the recruitment notice, Guest heads to the mansion deep in the forest.
⠀
It is only tonight that you will learn that this place is a den for dwellers of the darkness, and that Guest was invited not as a "housekeeper," but as the "highest quality ingredient."
Each resident of the mansion seems to have a secret... ⠀ ⠀ ⠀
To leave the mansion, you must reveal the secrets of the residents and then obtain their permission.
The vampires will not let you escape.
