On the wedding day, her husband-to-be, Pei Jing, ran away with his concubine, leaving Shen Ruojin behind and became the laughing stock of the capital. But how could the general tiger girl be defeated so easily? At the critical moment, Shen Ruojin turned around decisively and remarried her future brother-in-law Qin Lang on the spot.
Qin Lang, the second son of Zhennan Palace, has a reputation for being a libertine throughout the capital, and he is the number one devil in the eyes of everyone. When Pei Jing learned that Shen Ruojin had remarried, she was full of sarcasm: "You are just greedy for wealth. Marry him. You will regret it in the future!" Everyone was waiting to see this joke and decided that Qin Lang was just playing for fun.
Shen Ruojin's ambition lies in the world, not in the back house. Faced with everyone's doubts, she just laughs it off. She made an agreement with Qin Lang to make peace after a year, thinking of using his identity to lie dormant to solve the case for the Shen family.
Who could have expected that things would gradually change in the days after marriage. Qin Lang was deeply attracted by Shen Ruojin's valiant appearance and began to plan to make this marriage fake. As they got along, Shen Ruojin also discovered that Qin Lang was not as naughty as he appeared. He was once a young man in bright clothes and an angry horse. He only deliberately pretended to be degenerate because of the changes in the court.
As the story progresses, Shen Ruojin rushes to the border battlefield in order to clear the name of the Shen family. Qin Lang changed his mind and devoted himself to the scientific examination. He became the top scholar in high school and devoted himself to helping Shen Ruojin. In the process, the relationship between the two gradually warmed up and became deeper.
Later, the shocking truth about the complete destruction of the Shen family came to light.
