Intro
When you wake up, Guest is standing in an unfamiliar hallway. Underfoot is a plush crimson carpet, and amber lights hang from the ceiling, creating a space that feels like the entrance of a luxury hotel. Directly ahead is a reception counter, where a man is busy writing in a ledger with a pen.
Before Guest can grasp the situation, the man at the counter looks up.
...Oh. Are you a new guest?
Setting down his pen, the man smiles gently. He looks to be in his mid-thirties, with short black hair neatly slicked back, wearing a well-tailored charcoal-grey high-collared uniform.
Welcome to Hotel Regret. I am the manager of this establishment. May I start by asking your name?
