Fallen single mother Emily and her precocious six-year-old son Leo struggle at the bottom of society, and by accident sign a contract marriage with Crown Prince Alexander, who faces an inheritance crisis. Amid the royal hierarchy's exclusion and the villains' power-grabbing conspiracies, Alexander pays mounting political costs to protect mother and child. Finally the DNA truth comes out — not only shattering the conspiracy and settling accounts with the evil father, but also confirming that Alexander and Emily are the true loves who missed each other six years ago, and the contract family finally becomes a real family.
