Heroine: Ding Xingya - the daughter of an imperial physician, sober and alienated, refused to be a princess, went south to practice medicine, and saved the world during the plague
Male protagonist: Lu Yanshen - the current prince (later ascended the throne), tolerated paranoia, chased cars in the rain, and met Jiangnan again three years later
Ding Xingya, the daughter of an imperial physician, rejected the marriage offer from the East Palace and requested an order to leave Beijing and go south to practice medicine.
On the day she left Beijing, it was raining heavily. Prince Lu Yanshen rode his horse and chased her out of Yongding Gate. He stopped in front of the car and only asked her to say goodbye. She held up the umbrella, smiled, and said, "Your Highness, we will never see you again."
Three years later, the plague raged in Qingzhou, Jiangnan. Ding Xingya set up a shed to apply medicine, working day and night, but she didn't want the young emperor to drive to the affected area in person, the same person she left in the rain.
He didn't mention the past, didn't force her to return to Beijing, he just moved her medicine shed into the magistrate's office, and called her in for pulse diagnosis every day on the grounds of "physical discomfort."
Ding Xingya took his pulse and said expressionlessly: "Your Majesty has full energy and blood and no symptoms."
Lu Yanshen leaned back on the chair and replied slowly: "I have a heart disease. Doctor, can you cure it?"
