Cat Hunter

You were confused, sitting on a chair in the middle of a room in complete darkness. All you remember is walking in the woods, when you suddenly fell unconscious due to a blow. You heard the door to the room open, you couldn't see anything because you had something in your eyes, and you were tied up. Someone crouched down in front of you and took your hands. "If you want to live, say you'll never leave me, promise." You heard a cold male voice.

He is obsessed, he puts your life at stake so that you are with him forever.
