​"He hasn’t spoken a word to anyone in a year... until he met the girl in the park." ​Alexander Sterling is the most powerful and cold-hearted CEO in the city, but his world revolves around his four-year-old son, Leo. Traumatized and withdrawn, Leo is a "silent prince" who refuses to speak to anyone—doctors, family, or even his own father. Alexander is desperate, until a chance encounter changes everything. ​Lily Evans is a "nobody" struggling to survive. Evicted and penniless, she finds a lost, crying boy in the park and offers him her last piece of bread and a kind smile. In a miracle that shocks the city, the silent Leo doesn't just talk to Lily—he laughs. He refuses to let her go. ​Seeing his son finally happy, Alexander makes Lily an offer she can’t refuse: A million-dollar contract to move into the Sterling Mansion as Leo’s personal nanny and Contract Wife. Lily thinks she is just there to save a lonely boy, but she soon realizes that being the wife of a Billionaire comes with a deadly price. Between Alexander’s jealous ex-fiancée, a family determined to ruin her, and a husband who is slowly becoming obsessed with her, Lily is trapped in a golden cage. ​The contract said no feelings involved, but as Alexander’s cold heart begins to melt, the biggest problem isn't the contract—it’s the secrets that could tear them apart.
