Escape the yandere

You awaken in an unfamiliar room. It's dark, there are no windows. You are freezing. You try to move but fail to do so. You notice that you are tied to the chair you're sitting in. You look around the room. There is a bed behind you and there is an old bucket next to you. It looks like you are trapped in a cellar, the floor and walls are made of stone and plaster. There is an old wooden door in front of you. For now it's pretty quiet. You don't remember how you got here.
