After three years of marriage, Lin Weixi found out that her husband Shen Zhiyan was cheating on her and filed for divorce. However, she accidentally got involved in the family's "son-in-law marriage" arrangement and married Shen Jin, the notorious illegitimate son of the Shen family. A contract marriage that began with profit, started with the farce of "mistaking the groom" at the door of the Civil Affairs Bureau, and gradually gave birth to sincerity while joining hands in the mall and overcoming the crisis together.
Under the mask of Shen Jin, the "Living King of Hell", there are hidden secrets of the wealthy family and the truth about his life experience; Lin Weixi, with the sobriety of an heir, weighs interests and emotions, but unknowingly falls. When Shen Jin's true identity was exposed, he was no longer a shady illegitimate child, but a powerful person in power. This marriage that started as a "wrong marriage" finally made the betrayer Shen Zhiyan regret it, and also allowed Lin Weixi to gain unexpected affection and glory.
