Adopted by middle classed parents, Xiao Mai (Angela Chang) has always had a dream to be an heiress. Finally, her dream becomes reality. Xiao Mai discovers that her biological grandfather, Huangfu Xiong (Emp) (Gu Bao Ming), is the head of a prestigious aristocratic family. After being kidnapped by their family’s enemies and after many years of searching, he finally finds his long lost granddaughter.
As she starts her life as an heiress, everyday is filled with excitement; however, everything seems a bit different from what she had imagined it to be. In the family, there are 4 candidates, one of whom will become the successor of Emp. One of those candidates is Nan Feng Jin (Wu Chun). At first, Nan Feng Jin dislikes Xiao Mai because he knows that he will be engaged to Xiao Mai and as a result, can never leave the Huangfu family and will be forced to be the successor of Emp.
Because Jin wants to be a normal sales person, he tried his best to ignore his growing fondness for Xiao Mai, but love prevails. Initially, the two want to hide their relationship from Emp, because they fear that exposing their relationship will result in their engagement and Jin’s establishment as Emp’s successor.
Then one day, a new ‘Huangfu Shan’ appears that has the same birthmark and evidence that she is the real Huangfu Shan, such as a ring with her birthdate encrypted in it. Xiao Mai and Gong Mo Li, the ‘real’ Huangfu Shan, have the same interests and birthdates. As a result, Xiao Mai gets kicked out of the household and instead becomes a maid in the Huangfu house. She later discovers a plot invented by Gong Mo Li and Emp, where Gong Mo Li is pretending to be the ‘Huangfu Shan’ and in love with Jin. In reality, Gong Mo Li is in love with Cai and is merely an actress hired by Emp to make Xiao Mai and Jin confess their relationship such that they can become engaged.
Although the four try to confront Emp, he keeps hiding, with the help of Butler Yi. Soon the group eventually face Emp and tell him that Xiao Mai doesn’t want to be the heiress anymore, and that neither Jin nor Cai doesn’t want to be the successor. Emp becomes furious and lets them do what they want: “starting from scratch”, and kicks them out of the house.
Jin, out in the real world, is unable to find work because of Emp’s influence, however he manages to find a job as a construction worker. Cai And Gong Mo Li, who were also kicked out of the Huangfu House, start selling their things to the pawnshop but end up spending their money on useless things. Eventually, Cai and Gong Mo Li give up and returned to the Huangfu House.
Over time Emp becomes ill and has to go under operation. He has kept his illness a secret, something that only Butler Yi knows about. Even though his condition is becoming worse, he still doesn’t want to go under the knife. When Xiao Mai learned about his illness, she realizes that her grandfather’s stubbornness could lead to his death. She confronts Butler Yi and tells him to get Emp to agree to surgery and that if he is angry, that he can blame her.
The operation is successful, but Emp remains unconscious following the procedure. If Emp does not wake up in the days following the operation, the co-owners of the Huangfu business will take over his company. Even though Xiao Mai is the heiress, the co-owners do not believe that women, and Xiao Mai in particular, are capable of running the company. But Xiao Mai tries her best and takes the same exams that were previously taken by Jin and the other 3 successors (Cai,Ying and Lin) to prove her worth. Unfortunately she fails her exams, but just as the co-owners are about to take control of the company, Emp awakens. He insists that Xiao Mai is to become his successor and as a result, Xiao Mai ends up being both heiress and successor. Jin, on the other hand, remains an office worker.
Following the announcement, Xiao Mai has to go to America for a 3 year long course to learn how to become the successor for Huang Fu Corp. Jin is waiting for his clients to sign his first big contract which he stayed up the night before working on. Emp and the Nan Feng boys (other than Jin) are at the airport sending Xiao Mai off. As the time to leave nears, it appears that Jin will not make it to the terminal before Xiao Mai is to leave. However, just as Xiao Mai is walking towards her gate, Jin finally appears and calls out her name. She smiles and turns to him. Jin runs towards her and they share a kiss.
