Lydia Lum/Lydia Woo, a popular
Hong Kong restaurateur/
caterer and widowed mother to two children – 14-year-old daughter Apple Lum and 10-year-old son Jordan Lum – are forced to relocate when her
dim sum establishment is hit with a case of food poisoning after she hosted an event and is ordered by the authorities to close her business (she is labeled "dim sum killer" by her former patrons, even though she is unaware that someone falsely accused her so they could force her out of business). This new locale happens to be
Singapore. This is because her late paternal grandfather's best friend (referred to as Ong Ah Kong) had written a will giving her half-ownership of the
semi detached house he had
built thanks in part to his success in the
seafood business – as well as the fact Ong Ah Kong's life was saved decades before by Lydia's late paternal grandfather. However, when she arrives at the
semi detached house, it is already occupied by Ong Ah Kong's paternal grandson Billy B. Ong (Billy Boy Ong), who Lydia calls "Billy Bong". Billy prides his rise to the top of the ladder on promoting his
company's specialty,
fishballs. The presence of Lydia does not sit well with Billy at first, but he does give in because it might be the only way to get Lydia to give up her part of the house. Additionally, her
dim sum business brings in
customers and
clients for him. Other characters include Billy's 14-year-old son Max Ong, an aspiring
anime artist and a
Secondary 2 student, Ronda Chieng, Billy's
assistant and
secretary of Billy's owned
fishball company who is trying to pursue Billy and sees Lydia's untimely arrival as a threat to her plans at winning Billy's heart, despite the fact that his wife Suzanne Ong, who ran out on him, shows up in the 3rd season. She would later eventually lose interest in Billy in the 4th and final season. Others include Sulaiman Yusof, a former
stuntman and currently a
maintenance man and
blue-collar worker of Billy's
company and Fruit Woo, an
antique art dealer and Lydia's younger brother from
Hong Kong. == Cast ==
