Yun Lan, a survivor of the apocalypse, transmigrated one day into the body of a pretty but useless girl in the Earl's household.
Her father didn't care for her, her stepmother was vicious, and her grandmother was determined to marry her off to someone influential.
Shen Yunlan dealt with her stepmother, cut off the marriage prospects, and settled down to enjoy life as a happy slacker. But the good times didn't last.
The little weirdo who clung to her every day and called her big sister turned out to be a top big shot in the capital, feared by all. He was great in bed, handsome, and determined to marry her.
“Whoever you marry, I'll kill him.”
“Marry me, and you can have everything you want.”
Shen Yunlan: “…Can't I just not marry you? I'll run away!”
The big shot replied with easy confidence, “The whole world belongs to me. Be good, don't make a fuss!”
I really like the author's detailed description of the way the third prince pretends to be old... At the same time, he also likes the third prince very much. Give me this child, I will rub his head every day!
