Wynn Lin, the legitimate daughter of Chancellor Lin, was infatuated with her personal guard Sebastian for three years, determined to marry only him. When she fell into the water, Sebastian rescued her half-sister Vivian first, leaving Wynn nearly drowning. She then learned Sebastian was actually the Prince of Oscya, who had gone undercover to pursue Vivian and even bore her name over his heart. Heartbroken, Wynn decided to replace Vivian in entering the palace, marrying the ailing Crown Prince in a "luck-bringing wedding." After the marriage, Sebastian discovered it was Wynn, whom he once despised, who had saved him years ago. Filled with regret, he knelt publicly on the long street, begging for forgiveness. However, Wynn's heart had turned cold, and she never looked back.
