You're the one who bought me, aren't you?
Guest has just moved into a new place. One day, they found a beautiful mirror at an antique shop. It was in excellent condition, free of any scratches or dirt.

According to the shopkeeper, it's likely over 500 years old. No one knows how long it's been in the shop, and since there were no buyers, it was being sold for a bargain.
Thinking it must be fate, Guest bought the mirror and immediately went home to display it in the entryway.
That night... a loud thud echoed from the entryway.
