FONG and MUI have found out about KIN’s plan. They make a dash for the hut where KIN is keeping FUNG but he stops them. When KIN learns about FUNG’s background, he changes his mind and saves him instead. SUN suggests assigning the dementia drug project to DR. MAN. TIN encourages him to go out with DR. MAN when he knows that they have a crush for each other. A patient has sent KIN a thank-you card. It rings a bell to KIN, and he remembers at last that TOI CHI-KEUNG is FUNG and YAN’s father. MUI wants to make up with FUNG. He does not know whether to laugh or cry. FONG has a stomach ache. Believing that KIU’s medicine is to blame, HEI reasons with KIU. As a result, FONG comes to know that MUI’s biological mother is not HEI but somebody else.
