On her wedding day, fashion designer Eve is left standing outside the groom's door—humiliated by a fiancé who never loved her. Then bold five-year-old Phoebe Thorne rides up on her bike, decides the beautiful bride is perfect for her guardian daddy, and carts her off to the Thorne estate. Grant, the cold billionaire CEO who raised Phoebe as his own, protects Eve from her ex and offers a contract marriage to help her save her father's legacy. But their paper marriage is about to turn into real love—and a ready-made family of three.
