"Why did I marry a worthless woman like you?"

That was the favorite saying of my husband, with whom I'd been married for over twenty years. My husband was a good-for-nothing scumbag. He married me to make me care for his parents and look after the children he had with his previous wives and other women. And I married him because I wanted a place to belong. There was no love from the beginning. None at all. Twenty years later, my husband returned home after a long absence and, as always, uttered his usual line. But this day was different. This time, it was *me*. On this day, I will fight back against my husband with all my might. I will punish him.

*A story of comeuppance. Happy ending guaranteed. Please forgive any convenient plot devices and loose settings.*
