Four years ago, on a thunderstorm night when the hotel lost power, down-and-out heiress Chloe walked into the wrong room, and spent a whole night with Alexander, the top tycoon who suffered temporary blindness after a car accident. She fled in a flurry at dawn, and the half "Sun" pendant she left behind was picked up by her vicious step-sister Sarah, who then falsely claimed to be the woman that stayed with Alexander that night.
Four years later, Chloe is hanging by a thread due to severe heart disease. Lily, her 4-year-old genius hacker little sweetie, to cure her mother, relies on the ice-blue eyes that are exactly identical to the richest man's, brings the remaining half "Moon" pendant and breaks straight into Sterling Group to recognize her father! Faced with the cold and paranoid biological father, and the scheming green-tea step-sister who obstructs them in every possible way, the mother and daughter are forced to sign a "cohabitation contract" to move into the manor. As the smart little kid slaps the detractors in the face with her high IQ tricks, the DNA fraud conspiracy is exposed, and the sun and moon tokens fit together into a complete whole, Alexander finally recognizes the long-lost white moonlight in his heart. After surviving a thrilling rainy-night kidnapping, dark web assassination interception, and a life-for-life heart transplant surgery, the once overbearing, unruly Alpha CEO launches his humble "chase wife crematorium" mode, and finally arranges a globally-stunning century wedding for her on a private island.
