The heroine Yuan Youlan is a modern Chinese and Western medicine practitioner and a top national agent. She also loves archeology and can be said to be versatile. However, she accidentally traveled through the desert to Su Fanqing, the eldest daughter of the ancient Protectorate. The original owner was pushed into the lotus pond and drowned by his two sisters. From then on, Yuan Youlan became Su Fanqing. She changed her cunning, domineering, arrogant and ignorant temper in the Hou Mansion, and carried out a series of reforms in the Hou Mansion. She only wanted to live a stable life as she pleased, but she didn't want to provoke such a charming and cruel prince. It's good for everyone if we don't touch the bottom line. However, what's the point of giving in to yourself and pampering yourself again and again? "After so long, your heart should be warmed up no matter how cold it is. Is it time to consider our marriage?" "Uh, my lord, are you sure you are serious about this matter? You only want to win the heart of one person and stay together forever. If you marry me, I will be the only one in this life. You have to think clearly."
