After Becoming the Female Lead of a Torment Novel, I Turned the Tables and Tormented Everyone Else

A shameful relic from my past, don't read it!!! Please, please, please, spare me some dignity. [Golden Finger!] [Brilliant Heroine!] [Past and Present Lives!] [Destined Love!] Shen Lou was the head of the country's top research team, young and promising, with a bright future ahead. Then she set herself on fire and died in the lab. She opened her eyes, and lo and behold, she'd transmigrated. System: Hello, Host. This is Matchmaking Official 520. Please do your best to change the bad ending. Only after calming down did Shen Lou figure out that she was in the Min Dynasty from the history books, and that this bad ending referred to a famously vicious couple who loved and fought each other, each waking up every day thinking about how to kill the other. The famous Marquis of Pingyang and his wife. You've got to be kidding. Anyone who's studied history knows those two were mortal enemies, and the Marquis of Pingyang killed his wife. And she, a straight-laced woman in science and engineering who'd never dated anyone by the age of twenty-eight, was supposed to turn a bad ending into a happy one? Shen Lou: What if I don't? System: Oh, then the male lead will kill you. It will hurt a lot. Shen Lou: ??? This damn world must really hate her. Shen Lou didn't know that the wife of the Marquis of Pingyang was actually her past life. Her parents had died young, her elder brother treated her like a chess piece, and even her husband was wary of her. She had little left to cherish in this world, so after accomplishing her great cause, she lay down in her coffin without a care. But when the truth came to light, everyone she'd thought didn't love her went mad. With her past life beginning anew and memories of her previous life surfacing, Shen Lou had a headache. Who should she listen to apologize today?
