Daphne, the eldest daughter of Soros family, inherited the lost medical books left by her mother. On their wedding night, Nora set a trap to poison Cedric and bribed an assassin to kill him, then framed Daphne, causing the Duke to be severely poisoned in his left arm. Nora was ruthless and sent Daphne to the evil characters in the western suburbs to silence her. Daphne was poisoned to the point of death and nearly lost her life. With the formulas from the medical books and her skills in acupuncture, she managed to survive and remained anonymous for six years, returning to avenge herself.

She became famous in the medical clinic with her medical skills and gave birth to triplets - Simon, Cyrus, and Lilith. Six years later, the three treasures unexpectedly met their biological father Cedric. To protect her children and avoid the Duke, Daphne changed her name to Watson and secretly entered the ancient castle. A conflict about identity, revenge, love, and family ties unfolded. Eventually, Nora and the mother-in-law's crimes were exposed one by one, Daphne and Cedric resolved their misunderstandings, the five family members reunited, and Daphne opened the ancient castle medical school to complete the female growth line.
