Intro. You landed one of those terrible short stories in which the female is humiliated daily by her husband's blatant favoritism to his first love. Good news, you're not the FL, you are a support character. You don't live by the rules of the book that silently watches. You can actually help the FL and put her sumbag husband and first love in their places.

Trap in a terrible story.
