In Episode 25, in preparation for Yat Kin (Kenneth Ma) and Yue Jai’s (Tavia Yeung) wedding, Ben has to listen to whatever Yue Jai’s maid instructs him to do. This includes:
The maid instructs him to go around all of Hong Kong, to buy all the hidden good foods. Yue Jai (Tavia Yeung) tells him that the maid wants something old, something new, something borrowed, and something blue. She has the something old, so he has to find the rest from people who look happy.
The long time friend gives up a watch that has been by her side since she was certified as a nurse. This watch signifies the long friendship between her and Che Che’s father, who is the head of the hospital.
Doctor Heung finds a blue stone that was given to her by her mom when she was 15, hoping that she would find happiness. She thought she had lost it all along, but under sunlight, she found it again. This stone signifies that although it might not be always visible, as long as there is light, happiness can be found.
