After Exchanging Marriages with My Younger Sister, She Married the Richest Man and Was Doted on by Her Husband.

Si Yuning and her sister died in the fire together, and were reborn together. In the previous life, my younger sister rushed to marry Wei Wenjing, the richest man. The whole Internet envied my younger sister for being the wife of the richest man, and laughed at her for marrying Mr. Pei, a low-ranking member of a wealthy family. As a result, Wei Wenjing died suddenly just after her sister got married, without seeing the groom. The Wei family went bankrupt and was reduced to serving as a party host. However, the young man she married, Mr. Pei, became the new richest man. He also doted on his wife and became the favorite of a wealthy family. The younger sister was so jealous that she and Si Yuning died together. When she opened her eyes after rebirth, her sister snatched away the token to replace the life-saving grace she had given to Mr. Pei. She planned to marry the future richest man and take away her life. Si Yuning smiled and handed over Mr. Pei. He was a maniac who doted on his wife and a group favorite. He was simply a perverted domestic violence maniac. Let her marry Wei Wenjing on her behalf? Si Yuning even accepted it with a smile. She was young and widowed, and could earn a salary of one million just by lying down. It was so cool! Just three years after their marriage, Si Yuning looked at the lively Wei Wenjing and asked, "Where's the promised sudden death?"
