Marriage Contract

After her husband dies, leaving her with a substantial amount of debt, Kang Hye Su (Uie) struggles to raise her daughter alone. To make matters worse, Hye Su learns that she has an inoperable brain tumor, making her situation even more dire. An unlikely savior comes in the form of Han Ji Hun (Lee Seo Jin), the head of a restaurant company, whose mother needs a liver transplant. Hye Su and Ji Hun make a deal: if Ji Hun will provide for her daughter, Hye Su will donate her liver when she dies. But what begins as a cold, transactional relationship slowly evolves as they navigate the complexities of their fake marriage, family expectations, and the undeniable bond forming between them as the inevitable end grows closer.
