Su Nianwan never thought that on the day her sister fled the wedding, her father would use her as a substitute and put her in the wedding car.
The groom's name is Pei Yan, a name that is talked about by everyone in the capital's business district. Rumor has it that he started from scratch, had blood on his hands, and had a heart of hell hidden under his suits and leather shoes. On the wedding night, he did not step into the wedding room. He only sent someone to deliver a message - "Be your Mrs. Pei peacefully and don't cross the line."
Su Nianwan was happy and pure. She married into the Pei family not for love, but to find out the truth behind her mother's mysterious death seven years ago. All the clues point to one person - her mother-in-law, Pei Yan's mother, Song Jinhua, whose hands and eyes are as bright as the sky.
Holding back her hatred, Su Nianwan became a well-behaved and obedient young lady in the Pei family. During the day, she was made difficult by her mother-in-law and ostracized by her sister-in-law, but she tolerated it one by one. At night, she secretly collected evidence and stepped closer to the secret that had been covered up for seven years.
However, she missed one thing - Pei Yan.
This man who was supposed to be indifferent to her began to care about whether she had been wronged. He began to protect her in his arms on thundery nights, and began to say in front of everyone: "Who dares to touch my wife, Pei Yan?"
Her disguise was melting, and his coldness was disintegrating. Just when Su Nianwan thought she couldn't hold on any longer, she finally found out the ultimate truth about her mother's death——
It was not Song Jinhua who handed out the poison on that rainy night.
It was the person she had always trusted, who provided her with clues, and who promised to help her get revenge.
And Pei Yan knew everything from beginning to end.
