Pastry chef Sophie accidentally entered a room five years ago and had a one-night stand with the tycoon Roman. She mistakenly believed a greasy rich second-generation heir was the man from that night and later gave birth alone to their genius hacker son, Leo. Five years later, Leo hacked into a database to identify his biological father, then orchestrated his mother's employment at the Roman Group. When Sophie and Roman reunited, misunderstandings abounded. Vanessa and Gary repeatedly spread rumors and framed them. Leo intervened multiple times to protect his mother, publicly presenting a DNA report to reveal his true parentage. Roman lavished shares and a manor upon the mother and son, doting on them immensely. They teamed up to settle scores with their enemies and held a wedding of the century in Central Park. The family of three lived happily ever after.
