Mandy Wong
Ka-Hong and his pregnant wife (first grandson to the Kwan family), Lau Siu-Lan (Mandy Wong), lived in one of the very estates that Wang-Chim wanted to buy, rebuild, and re-sell. Originally, Wang-Chim dispatched his personal assistant to help finalize the contracts and would pay Ka-Hong a large favorable sum of money. Unfortunately, Siu-Lan's shrewd and greedy nature wasn't satisfied with the amount. She felt that Ka-Hong should've haggled more as she knows Wang-Chim wants the building badly. To that end, Ka-Hong relented to his wife and he canceled the contract signing.
