Shen Manqing, the heir to a top wealthy family, is dissatisfied with his family's marriage. He unexpectedly meets Lin Shen, a taciturn truck driver, and falls passionately in love at all costs. Although Shen Manqing is extremely intelligent, she is a complete "love brain" emotionally. Even if she faces all kinds of difficulties from her vicious stepmother and the poor life of her husband's family, she is happy with it. However, Lin Shen's true identity is far from being as simple as an ordinary driver. He is the only bloodline of a top-notch family who was persecuted by his evil stepmother many years ago and lives among the people. In order to protect Shen Manqing, Lin Shen has been enduring humiliation and making plans in secret with his excellent mind. The whole book revolves around Shen Manqing's battle of wits in the conflict between mother-in-law and daughter-in-law, Lin Shen's "pretending to be a pig and eating a tiger" to hide his identity, and the two's eventual fight against the vicious stepmother and return to the top.
