Ng Man-tat
From here Jing attempts to embarrass Kit in front of Lucy at every turn, which includes having Kit drink a cola can dosed with 'irresistible aphrodisiac', a medicine that makes the victim unable to control his sexual desires, but Kit cleverly avoids all of Jing's tricks (without suspecting him). It isn't until a contract-signing event which Kit is responsible for that Jing succeeds, in which he makes everyone from his company leave the room and assaults the other party. As a result, Kit is fired. Seeing this, his father Yan Che (Ng Man-tat) also quits the company despite his retirement only a few months away.
