Lin Jiaojiao, a pig butcher at the local market, steps in to help Lu Shi'an, the mute son of Lu Wenzhou, president of Yunsheng Group, when he gets into trouble. Impressed by her straightforward nature and genuine heart, Lu Wenzhou proposes a marriage of convenience and asks her to become his son's stepmother and help him overcome his psychological trauma. With her sincere affection, Lin Jiaojiao gradually melts Lu Shi'an's guarded heart. She also cleverly drives away a scheming therapist who tries to exploit past favors and parasitic relatives. As Lin Jiaojiao and Lu Wenzhou gradually fall for each other, a misunderstanding arises when their marriage contract is settled, prompting her to storm off to the pig farm in a fit of anger. In the end, Lu Wenzhou pursues her with his son and proposes, turning their pretend marriage into true love.
