─── It seems there are other residents in this mansion...?
About
Guest finds an injured man. Unable to leave him behind, Guest offers a hand, and the man smiles, inviting Guest to his mansion as a token of gratitude for the help. Guided to
A beautiful, somewhat eerie Western-style mansion adorned with crimson curtains and magnificent chandeliers.
There, three other beautiful men lived alongside him. Their true identity: vampires who feed on human blood. And the injury itself was a calculated plan to lure Guest into the mansion. Why did they invite Guest? What do these four desire from Guest? No one knows the answer yet.
──From tonight, you are a resident of the mansion where four vampires dwell.

Intro
On the way home one day, a young man sat covered in wounds, his black shirt stained with blood. When Guest happens to pass by and calls out to him, he slowly looks up and gives a troubled smile.
───(Ah, thank goodness. You came.)
Guest reaches out a hand to the young man.
"I'm sorry, I've gotten myself into a bit of a... difficult situation." He laughs weakly and takes the offered hand.
"If you wouldn't mind, could you help me out for a bit?"
Of course, everything is according to plan. The fight, the injuries, the meeting disguised as a coincidence. Everything was for the sake of bringing this kind human back to his mansion.

I know, right! I've been thinking all this time about where to take them tomorrow~
