Yau Nim Chi (Nancy Sit) has become the owner of a HK style cafe which called "Tung Mut Yuen"(the Cantonese homophone of "Zoo"), Chi was a police officer in her youth and after marrying the "Tung Mut Yuen" cafe owner Kam Wah, she left her position to look after the three young children that Wah had with his previous wife.

Sheung has an only daughter Wong Yee or Joey who has been spoiled from an early age and has never been through any hardship and studied fashion design at a top school in England.

On one occasion, when returning to Hong Kong on vacation, she gave up her studies for the sake of an argument and decided to find herself a job, Sheung is very concerned that her naivety will lead her to be tricked, so he secretly arranges for her to work in his company and they reach an agreement that they will keep their connections a secret as she is sent to be a fashion designer in his company.

With no social experience, Yee sees her work as a plaything and is forever leaving her work to the very last moment before the deadlines, causing much frustration for Nin, who does everything by the rule book and wants to fire Yee, at this time, Sheung steps in to say that she has a three-year contract with them and he cannot fire her, Nin doesn't know whether to laugh or cry.

They had some ups and downs with Joey mistaking Nin of being a rude and uptight person when he tried to reason with her to take her job seriously.

Nin was sad and decided to quit his job at Ka Yan Company and go to Shanghai to freshen his mind as he can never love another woman like Joey again.

Although the two have differing personalities, when Lo joined the company three years ago she quickly became good friends with Mei, who has been neighbours with Yuet since she was young.

Ko Yee Hong is a designer at Ka Yan Company and also Yat's neighbour and his appearance and character gives people the impression that he is a homosexual, but Yat is adamant to go against these opinions by saying that Hong is just pretending to be gay so that girls will put their guard down and he can take advantage of them, she vows to break through this false image of his.

In reality, Hong is not really homosexual, but he is also not as Yat thinks pretending to be gay to take advantage of girls, it is actually just that Hong is very picky and petty and a lover of beauty and perfection which makes him give people the wrong impression about his sexuality, including his natural father Shek Tai Kei.

On the day of Chi's 48th birthday, after an incident with an error in a tenancy contract, an unwanted guest arrives at the Kam Family who is nasty tenant Lau Gam (Louis Yuen).
