After the Frail Prince Recovered from His Illness, the Stepsister Regretted It

As we all know, the eldest son of the Duke of Zhenguo accidentally encountered poison while investigating a case. The imperial doctor was helpless and concluded that he would not survive the winter. The stepsister was engaged to the prince, and when the town government requested that the engagement be fulfilled in order to celebrate the prince's happiness, she cried and argued in the palace not to get married, which made the elders in the family feel distressed. Because they didn't want my step-sister to become a widow at such a young age, they actually married me, a person with a foreign surname, into the Zhenguo government. I studied medicine with my mother since I was a child. I traveled around and saw many cases. The strange poison in the young master of the Zhenguo Palace was just a minor problem in my eyes. Under my care, he recovered to health and resumed his position as the Young Minister of Dali Temple. When my step-sister saw that the prince was young and promising, she was ready to make a move, so she ordered me to come down and give up the position of the prince's wife. Ridiculous, is this the crown prince's wife who she wants to be? Have you asked the prince for his opinion? Intention: I will protect your husband!
