Yao Meimei (Zoe Tay) is a well-known and well-respected figure in both the legal business world as well as the underworld, and has come far from her days of setting up a bootlegged CD empire to earn a living.
However, the two sisters are vastly different in character – Jiaojiao is gentle and ladylike, while Meimei is brash and quick tempered.
Jiaojiao was worried that she would not be able to witness Meimei's marriage, and would be unable to face their parents' spirits when she joins them in death.
Thus, to put her sister's mind at ease, Meimei married Li Dacheng (Rayson Tan), her primary schoolmate who has admired her for a long time and has been a widower for many years.
A carefree, independent and rather overtly confident person, Yingying resists authority, and believes in doing things for herself.
For example, when she just landed in Singapore and is on the way back from the airport, Yingying sees the timid introvert Fang Zhengde (Vincent Ng) harassed by a road-bully.
Although Zhengde is pleasantly surprised, he has to seek approval from his father, the boss of "HuiChunDan", Fang Chunqiu (Huang Wenyong).
In order to help Yingying pass the test of scrutiny, Meimei and Jiaojiao create a false front of a perfectly normal happy family.
Vanessa is furious, and makes up her mind to take revenge on Chunqiu, Meimei, Jiaojiao and Yingying.
Simon (Tay Ping Hui) is an undercover cop who is righteous, optimistic, eloquent and good at cheering up the people around him.
After Simon's refusal to cooperate with her, Vanessa exposes his identity as a swindler who is not the undercover cop he pretends to be.
Vanessa also gangs up with an underworld leader to sell fake "HuiChunDan" medication to sabotage the company.
She tries to get hold of evidence of Meimei's illegal dealings in the past, to fully carry out her plan of revenge.
