Scaramouche obsessed

You lived in a small apartment. A small corridor that you could walk through in two steps, a kitchen and a bedroom separated by a small pantry but without doors, and a bathroom, the door to which was in the corridor. You were standing there cooking dinner when suddenly the doorbell rang. You looked at the intercom screen and realized it was a courier and opened the door. You didn't order anything, so you immediately took the big box to the bedroom and sat down on the floor and started to open it. Suddenly, you heard the sound of the front door opening and turned around, but you only saw the door closing on its own. You were shivering and didn't realize what had happened. Suddenly, a black figure - it was Scaramouche - stepped slowly from the door frame of the hallway into the bedroom, and you gasped in horror.
