Gu Heng was adopted by the Gu family for twenty years, and her grandfather announced her as the successor. At the family banquet, however, her adoptive mother drove her out of the house with a paternity test. Returning to the Lin family, she helped her parents seek justice, set up a factory independently, and won orders with her own hands. The Gu family forged documents and planned a car accident to seize family property, but their evil deeds were eventually exposed and they suffered legal sanctions. Gu Heng rescued her grandfather, guarded the Gu family business, and gained two warm families. Sincerity exchanges for sincerity, and kindness ultimately has a home.
