In order to protect his seriously ill grandmother, Ruan Shutong was forced to marry Jin Yanshen, the leader of the Jin family, on behalf of his stepsister. She got pregnant unexpectedly after marriage. She wanted to live in silence, but she discovered a shocking conspiracy: Jin Yanshen's second uncle, Jin Mingqian, colluded with his stepsister Ruan Manwei to use drugs to remove the fetus in her belly - because the child was the only legitimate heir to the Jin family and would block their path to power.
After learning the truth, Ruan Shutong fled Yuncheng overnight and gave birth to his son "Xiaotuanzi" incognito in a seaside town. She relied on her hidden design talent to make a living while secretly collecting evidence of the conspiracy.
Three years later, Jin Yanshen met Ruan Shutong by chance during a project inspection and discovered that "Little Tuanzi" was exactly the same as when he was a child. At this time, he has noticed abnormalities in the family: traces of his second uncle's misappropriation of public funds and the forged "Ruan Shutong accidental death" certificate by his stepsister, all pointing to the disappearance case three years ago.
Jin Yanshen started chasing his wife, clumsily trying to please his mother and son while secretly investigating the truth. Ruan Shutong was strictly defensive at first, but gradually softened under Xiaotuanzi's "magic assist". When Jin Mingqian sensed the threat and kidnapped Xiao Tuanzi to force Ruan Shutong to show up, the two finally joined forces: Ruan Shutong disclosed the evidence in the design manuscript (including the drug formula that was switched that year), and Jin Yanshen exposed the second uncle's financial shady, and finally sent the villain to the law. The conspiracy came to an end, Jin Yanshen begged for forgiveness while holding the paternity test form, and the family of three rebuilt trust on the ruins.
