Rakuin no Monshou - Volume 12, Chapter 1: Creeping Shadow

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. Finally, one day, she was photographed by reporters and posted online. "It's all your fault! You used so much force last night! The Jiang family is going to laugh at me again!" Fu Jiuxiao said, "With me around, no one will dare to laugh at you. Moreover, I will make them pay back tenfold for the pain that the Jiang family has caused you!"

She, a renowned assassin of the 21st century, actually crossed over to become Su Manor’s most useless good-for-nothing Fourth Miss.

Crying blood and tears, she pledged a poisonous vow. The gods did not fail her. She was sent back to a decade ago. The legitimate daughter of Jiang family returned from hell.

Keeley, a simple plain Jane, hits the jackpot. [No, she did not win the lottery!] At least that's what she thinks when she marries the most eligible bachelor in New York City: Aaron, a wealthy cold-hearted heartthrob and Tycoon.
