How Do I Get By After Becoming the Heroine of a Bad Ending Story?

[Do Not Read! My Cringey Past!!!] Xiao Ning had merely read an ancient-style Mary Sue romance about an overbearing CEO, but somehow she transmigrated into the book and became the heroine who shared her name... The original story had a tragic ending, a total BE. After transmigrating, Xiao Ning was so frightened she broke out in a cold sweat. She was determined to defend herself to the bitter end! System: Mission 1: [The Host must turn the tables on the male lead, restore her authority as his wife, and sing the song of a husband-servant rising to power.] Mission 2: [The Host must change the original ending, in which the male lead dies, and give the novel an HE.] Xiao Ning didn't dare slack off. She diligently completed her missions every day, but then she noticed that the original male lead's character was falling apart more and more... Why was the male lead, who used to treat her like trash, suddenly changing his ways?! A lucky heroine with fortune on her side x a sinister, ruthless dog emperor Also known as: "The Overbearing Emperor Falls in Love with Me" and "Today, Too, I Must Torment the Male Lead" Reading Guide: 1. The male lead is a total jerk at first, but later becomes a devoted puppy and henpecked husband. 2. Set in an imaginary ancient world. Both leads are virgins. Historical nitpickers, please stay away. 3. The author's writing is poor and the logic is dead. Read for fun, and don't read if it's not your thing. The inspiration for this story suddenly struck the author at 1:30 a.m. while eating spicy malatang... Author's Weibo: @Li Feibai Theme:
