thank you for the clarification. much appreciated. ok, I looked it up, and this is what I got -
In the tenements of New York City in the late 19th and early 20th century, apartments were built with bedrooms on top of one another. It was common to hear your upstairs neighbor take off a shoe, drop it, and then repeat the action. It became shorthand for waiting for something you knew was coming.

Yaoi always makes me nervous whenever something good happens I’m always waiting for the other shoe to drop lol
