Fuye, Sister Ni's Ex-Brother Is so Difficult to Deal With.

Ni Qiao was originally the youngest daughter of the Ni family, a century-old family in the imperial capital. She was pure and innocent, but she experienced three men who broke her heart in her best years. In the end, she was abandoned by her family and loved ones at the border. No one knows how she survived there. Five years later, she returned to the imperial capital, using a mysterious identity to investigate a murder case of a wealthy family. When she once again faced the upper class who had once admired her and spurned her, and met the three men again, she was no longer the ignorant young lady of the Ni family back then. She began to re-enter the sight of these upper-class people in order to uncover the truth. But the strange thing is that the three men who once abandoned her and looked down upon her began to circle around her, chasing her, and even gave up on those "true loves", and she suspected that the real murderer was in the family of these people... At the same time, the organization behind Ni Qiao told her that a chief was sent to assist her, but who could tell her why this chief was the living king of hell in the imperial capital - Fu Jin, known as Fu Ye? As the two get along on a daily basis and investigate cases together, they gradually develop feelings for each other. But as the case gradually became clearer, Ni Qiao discovered that Fu Jin seemed to be involved in the case. So, what should she do, and where will her relationship with Fujin go? Everything has become a mystery...
