The quick transmigration System selects a transmigrator and asks her to take the place of a supporting female character, change the course of her life, take revenge, punish scumbags, and turn her life around with a satisfying face-slapping comeback.
First world: [Scumbag Husband and Wicked Mother-in-Law]
Scumbag husband: You eat my food and live under my roof. What's wrong with asking you to look after my mom? Can't you just put up with it?
Cunning, calculating mother-in-law: Once my son has money, he'll dump you sooner or later.
The transmigrator kicks the scumbag husband and puts the mother-in-law in her place, going from a worn-out housewife to a wealthy beauty.
Scumbag husband: No! How did she get so beautiful? And she's dating a rich, handsome man!
Mother-in-law: Son, hurry and sweet-talk her into coming back. Then we'll have a mansion!
Transmigrator: Sorry, get lost and stay lost!
You treated me like I didn't matter back then, so now you'll never be good enough for me.
The story is all about indulgent sweetness and satisfying revenge.
