Tan Rou only learned that she wasn’t the Tan family’s daughter when she was seventeen years old. She went from being a rich young lady to living in the slums. The parents she adored belonged to someone else, and this series of knockdowns was hard for a seventeen-year-old girl to accept. She wailed like a child for the sake of proving this was all a lie. The vicious words she spouted had hurt her biological family but she didn’t notice. She thought the Tan family was her real family despite them seeing her as an eyesore, and was even naive enough to want to befriend the Tan family’s real daughter, Tan Jing. Alas, the latter drugged her drink and arrange for a thug to rape her. Tan Jing even brought their classmates along to catch them in the act so Tan Rou was now tainted for life. After being reborn, she looked down at the man she was stepping on. Tan Rou swore not to be a useless wretch in this life or be bullied to death.

Tan Rou scoffed upon hearing this. She held back her brother from trying to stand up for her. “We have all the time in the world. Let’s just wait and see.” Just as everyone was waiting for Tan Rou to make a fool of herself… A top-class perfumer, a top scholar, a world champion… The fake young lady’s multiple identities kept getting exposed one after another, bumping her up to number one on the trending search, shocking the world. Wait, where was the promised humiliation?

After the real daughter of the Jiang family fell sick, she became stupid and insisted on marrying the cold-blooded, cruel, and crippled Fu Jiu. Mother Jiang said, "So be it. She's a good-for-nothing anyway. I only asked her to marry in place of my sister." Father Jiang: "After you marry him, remember to ask 9th master to help your sister find a better marriage." The fake heiress said, "Sob, I feel so sorry for Sister, but… if you get beaten to death by the 9th master, the Fu family will compensate us a lot of money, right? I'm looking forward to it." Jiang Li sneered. She bid farewell to her hypocritical family and brought her shabby dowry to the Fu family. After having been reborn once, she knew very well that Fu Jiu was the only person who treated her well. Everyone was waiting for Jiang Li to be beaten to death.
