Through his observation, YAT-SING believes that Man Hing Primary School is an ideal school, and they even have a school nurse, which is very suitable for KEI MONG to enroll. SHIU-BONG needs more than half of a year to recuperate. He worries that the water recycling project - "Clean Water Project" that he initiated all by himself might end up being put on ice once SHIU-WING wields power, so he hopes his daughter to be the interim CEO for the time being and requests TAI-CHI to assist her.… ...

NGAI-YAN returns home, where YEE-LING pushes her to get married as soon as possible. Until then, NGAI-YAN comes to realise that it's her chauffeur, Uncle KEI, who disclosed the conversation between her and her boyfriend to YEE-LING, therefore she decides to change her chauffeur. KEI MONG is allocated to the school which is his 11th wish on his application, so LAI-SA urges YAT-SING to bring his son and go to Man Hing Primary School in person to see whether KEI MONG might have a chance to get a seat there. On their way to the school, they run into a car breakdown incident, during which YAT-SING helps NGAI-YAN drive her car away.… ...

NGAI-YAN and her father SHIU-BONG recall their days before. In those days, although they were poor, they were very happy.

It turns out that MAN-KWAN is the younger sister of YAT-SING's girlfriend, who always travels around by herself and attracts many suitors. Seeing that SHIU-WING reprimands CHI-HAU for not knowing how to distinguish himself from the others, NGAI-YAN instead gives CHI-HAU a lot of encouragement.
