Heir's Only Beloved Single Mother

Tina, a girl from the bottom of society, was raised in the home of her cruel foster mother, Ellie, who treated her as nothing more than a tool for making money. Six years ago, while working as a cleaner at a five-star hotel, Tina encountered Blake—the heir to a powerful family—who had been drugged by a rival and had lost control of himself. They spent one night together, and Tina slipped away quietly, later giving birth to their son, Danny, on her own.

Six years later, Ellie takes Tina to a matchmaking meeting, hoping to trade her for $300,000. Tina publicly declares she has a child, cutting ties with Ellie completely. Meanwhile, Blake's grandmother, Daisy, discovers Danny in a park—the boy's features and the star-shaped birthmark shared by the family are identical to Blake's. A DNA test confirms Danny is Blake's biological son. Blake launches a citywide, multi-million-dollar search for the mother and child.

Tina survives on freelance design work. When she goes to Blake's corporation to demand unpaid fees, she is repeatedly harassed by the fake heiress, Isabel. Isabel, who covets Blake, teams up with a lecherous director to trap Tina—luring her to a hotel and conspiring with the director's wife to frame her for seduction, intending to destroy her reputation. Each time, Blake arrives in time to protect mother and son, retrieves surveillance footage to clear Tina's name, and invites her to join the company as a designer.
