(Transmigrate into a book + Beloved by all + Tearing down scumbags + Rugged man + 1v1)
Cheng Wanning transmigrated into a book and became a commandery princess of the Dayi Kingdom, as well as a cannon-fodder supporting character who dies early in the story.
In the original story, her adoptive older brother falls for the heroine, Lou Yunyun, dotes on her, and is willing to give her everything.
But Lou Yunyun is a spy sent by an enemy kingdom. She goes to great lengths to marry her brother only to use him to uncover Dayi's secrets, then seize the chance to eliminate him, the emperor's right-hand man, leaving Dayi without a capable general.
In the end, Lou Yunyun succeeds. Not only does the Cheng family meet a tragic end, but Dayi is also destroyed.
Cheng Wanning is so angry she can only laugh.
So she decides to fight fire with fire: she'll take the lovesick route and make sure lovesick fools have nowhere left to go.
Her adoptive older brother, Cheng Chaoshi, says, "Little sister, I'm going to the palace to ask for Yunyun's hand. You'll give me your blessing, right?"
Cheng Wanning smiles instead of getting angry. "Big brother, I'm going to marry Sister Yunyun's father. You'll give me your blessing too, right?"
Cheng Chaoshi: "?"
There's no way he can give her his blessing.
Cheng Wanning doesn't care. She throws herself into pursuing Lou Yunyun's father while plotting to expose Lou Yunyun's true nature.
Then, when her adoptive older brother finally sees the light, Cheng Wanning immediately decides to dump Lou Jiu.
And so, one day...
Lou Jiu comes to visit. Because he steps through the door with his left foot first, Cheng Wanning breaks up with him on the spot.
Just as Cheng Wanning thinks she can finally make her exit, the rugged man pins her against the wall. "Didn't you say you'd give me ten kids? If you have one less, you aren't going anywhere for the rest of your life."
Cheng Wanning: "..."
Is it too late to say she was only joking?
Asking for a friend. It's pretty urgent.
