I was an unlucky young lady. I was kicked out of my home by my stepmother and chased by a group of men in black. Fortunately, he was lucky enough to survive jumping off a cliff and discovered family secrets, thus inferring that his relatives did not die of natural causes. In order to find the murderer, I sneaked into the house of Shangguan, who I had been engaged to since childhood. As the loyal butler of the Shangguan family, I have a headache over this young master Shangguan Yu who always likes to make trouble with me. During the fight, he actually fell in love with Shangguan Yu. I dare not forget the family feud, but Shangguan Yu wants to marry his half-sister. What should I do with my lost heart? Who is the final mastermind of the conspiracy?
