After Shen Qingci, the legitimate daughter of the Prime Minister's office, was reborn, she changed her past life of wrongly trusting a scumbag and causing tragedy for the family. She was determined to protect her family and avoid trouble, but she accidentally provoked Xiao Jue, the powerful regent. In her previous life, she was afraid of this ruthless prince, and only after her death did she find out that he had slaughtered all his enemies and even died for her. In this life, she deliberately stayed away, only to discover that this regent, who was rumored to be not womanizing, was actually a "jealous man" - he would be cold-faced when he saw her talking to other princes, he would secretly destroy love letters when he received them, and he would glare at her confidants even when they came near. From the confrontation at the palace banquet to joining forces to break the situation, Shen Qingci gradually reveals the deep love he has hidden for many years amid Xiao Jue's increasingly obvious possessiveness and jealousy. When the whirlpool of power intrigues resurfaces, and the scumbag villain presses harder and harder, she fights side by side with him, clearing the obstacles while dealing with the daily jealousy of this "jealous prince". The regrets in her previous life were finally made up for. In this life, she protected her family and accepted his full love.
