Nora, a girl from a poor background, has a one-night stand with Duke Julian, who was rendered infertile due to an injury, and gives birth to their son Leo. However, she is forced to abandon the baby at the duke's villa after local bullies seize the child. Ten months later, in order to find her son, Nora sneaks into the duke's manor posing as a wet nurse, and devotes herself to caring for the duke's adopted son—unaware that he is her own flesh and blood. As for Julian, who suffers from a severe aversion to the opposite sex, he develops an intense desire for Nora alone during their daily interactions. After overcoming numerous twists and turns, including a malicious housekeeper's schemes, the male lead's raging jealousy, and a fierce confrontation with the local bullies, the two finally uncover the shocking truth about Leo's identity and clear up the misunderstanding from that fateful night with the help of their love token pendant. In the end, the duke defies family pressure and marries his one true love in the grandest wedding, and the small family of three is finally joyfully reunited.
