Married but Available

Tony Au Yeung Tze-chung marries his girlfriend Chu Ming-ming abroad. Once back in Hong Kong, Chu Ming-ming goes back to work at Kam Bo Do (金寶多), a traditional enterprise at the top of the gold and jewellery industry. Chu Ming-ming is promoted by her boss, Carol, to be her personal assistant on the condition that Chu is single, thus, can be called upon at any time. In order to get the high salary job, Chu Ming-ming decides to hide her marriage from her boss. Coincidentally around the same time, Tony is also hired as a personal assistant by his best friend, Lucas Cheung, whom he met while doing his master's degree in America. Tony also decides to hide his marriage from Lucas. Later Lucas becomes a part of Kam Bo Dor's board members. Tony and Ming-ming then realize that they now work in the same company and Ming-ming's boss is Lucas' ex-stepmother, making Tony and Ming-ming to be on opposing teams within the company. The two bosses constantly power struggle to prove they are the better leader for the company. While serving their respective bosses and with the help of Chu Min-ming's friends, Candy and Shirley, the married couple constantly come up with stories and excuses to keep their marriage a secret from their bosses and other co-workers. Through his job Tony becomes reacquainted with Kay, Lucas' younger half-sister, who he met years earlier when she was a teenager. Tony had promised Kay that once she learns how to swim he will teach her to dive and show her the colourful world under the sea and find the beautiful mermaid. However, they lose contact and Kay, now an adult, has been hoping to find Tony ever since. Tony and Kay have a romantic relationship as does Ming-ming and Lucas. Will the romantic feelings tear apart friendships and marriage? Will ill feelings carry into the workplace? Later it is revealed that Lucas is going after a bigger fish than Carol. Lucas enlists Ming-ming to help him with this dangerous mission. Is there really a bigger and more dangerous enemy or is this Lucas' ploy for revenge on all who have wronged him? == Casting ==
