Ten years ago, Chung Siu-Hor, discovered that her husband Gan Tai-Cho was having an affair with their employee Yan-Hung. Siu-Hor and Tai-Cho owned a confectionery together known as the Moonlight Bakery. On the night of the Mid-Autumn Festival, Yan-Hung forces Siu-Hor and Tai-Cho to declare divorce. Each parent gained half the custody of their kids. Tai-Cho was given Wing-Ka, Wing-Yuen and Wing-Chung, while Siu-Hor gains custody over Wing-Ho, adopted daughter Hou-Yuet and mute daughter Wing-Hing. After the divorce, Yan-Hung and Tai-Cho take on the Moonlight Bakery name and prove successful, resulting in a family asset totaling HK$1 billion. Meanwhile, Siu-Hor struggles to make a living at the modest bakery she once owned with Tai-Cho. Over the next ten years, Yan-Hung manipulates the family to keep relations hostile. Tai-Cho's mother, Sheh Gwen Lai has a strained relationship with Siu-Hor, and Yan-Hung takes advantage of this to fuel arguments between the two sides. To try and separate the family more, Yan-Hung sends Wing-Chung and her daughter Yue So-Sum to study in England. When Yan-Hung has a miscarriage with Tai-Cho's baby, she blames Wing-Yuen to make him feel indebted to her. Meanwhile, Siu-Hor's sister Chung Siu-Sa comes to Hong Kong after divorcing her husband. Siu-Sa is very angry that Siu-Hor let Tai-Cho take the Moonlight Bakery name and decides to sue Yun-Hung and Tai-Cho for the Moonlight Bakery franchise. However, Siu-Sa ultimately loses the court case. Wing-Ka lacks interest in managing the bakery; instead, he is addicted to the stock market. With Siu-Hor and Hou-Yuet's encouragement and support, he is able to quit gambling. Wing-Ka eventually falls for his cousin, Siu-Sa's daughter, Ka Mei. However, it is later revealed that Ka Mei is sneaky, selfish, and a greedy liar; just like Yan-Hung. The two form a partnership to break the relationship between the two families. Later in the series, Wing-Ka is revealed to have a heart disease. Wing-Ho finds himself in a complicated relationship with So-Sum. They dated back when they were 13, but they broke up when So-Sum had to go to England. When she comes back, the two fall in love again. However, the appearance of Dr. Ling Chi Shun causes So-Sum to abandon her feelings for Wing-Ho. She and Chi-Shun begin a relationship, but as it turns out, Chi-Shun already has a girlfriend named Wing-Lam. Despite Chi-Shun not having feelings for Wing-Lam, he feels indebted to her because she had helped him so much in the past. Later, he leaves for England with Wing-Lam, causing So-Sum to break down and cry. Wing-Ho helps her get over her feelings for Chi-Shun, especially when So-Sum finds out that Chi-Sun and Wing-Lam married. However, it is later revealed that they never got married and Chi-Shun just wanted So-Sum to get over him. Hou-Yuet finds herself constantly in arguing with her aunt Siu-Sa, who often refers to her as "quota." Feeling that she doesn't belong with the family, Yuet runs away. However, she sees how concerned her family is about her and apologizes and returns home. Later, she begins developing feelings for Wing-Ka, however the appearance of Ka Mei causes Yuet to become jealous. She tries to reveal Ka Mei's true colors, but no one believes her. Finally, Siu-Hor sees Ka Mei's true face and expels her from the family. Wing-Yuen is the one child that sided with Yun-Hung, due to him believing that he was the one who caused her miscarriage. After breaking up with Wing-Ka, Ka Mei begins dating Wing-Yuen, despite the protest of his siblings and mother. He later has a baby with Ka Mei, but, unsure if it is his, Ka Mei gets an abortion to avoid complications. Wing-Yuen refuses to believe Ka Mei is a bad person, but when he finally sees Yun-Hung for what she is, she blackmails him, threatening to reveal that he crashed into a person and ran away. Wing-Hing was constantly made fun of as a child, due to being mute. She decides to skip her chance to go to university to help Siu-Hor in the bakery. Wing-Ho constantly tells her to find a real job, and she finally gets a job as an office clerk. There she meets Kelvin, who begins to fall for her. Initially, Kelvin's mother is against the relationship, but she eventually accepts Wing-Hing and allows them to get married. Wing-Chung was separated from his family at a young age, being sent with So-Sum to England. His grades were very poor and he didn't like university. Siu-Hor, seeing how much her son dislikes school, allows him to drop out. Yan-Hung and Gwen-Lai are furious that he returned without telling them. Gwen-Lai, however, sees how happy Wing-Chung is now and allows him to stay. Despite Yan-Hung's actions, the family is able to re-build their relationship with each other. Yan-Hung becomes jealous and finally decides to take legal action against Siu-Hor and Tai-Cho, wanting to take 80% of the family assets, leaving them with a mere 20%. To prevent Gwen-Lai from gathering evidence for the court case, Yan-Hung kills her. Despite losing the lawsuit, the family is still very happy. Wanting to destroy their happiness, Yan-Hung tells Ka Mei to hold a meeting to reveal that Wing-Yuen killed someone. However, seeing the error of her ways, Ka Mei instead reveals the Yan-Hung killed Sheh Gwen-Lai. Due to the turn of events, Yan Hung faces murder charges. She tries to convince So Sum to lie and give false testimony and So Sum pretends to agree. Yan Hung later gives Sum 70% of her shares of the Moonlight Bakery as a present for So Sum and Dr. Ling's "marriage". Sum subsequently returns the shares to Tai Cho and Siu Hor and tells Yan Hung she'll tell the truth behind Gwan Lai's death. Yan Hung is convicted and sentenced, while Tai Cho tells her that he'll give her 50% of the shares once she finishes her jail sentence. Wing Ho and So Sum finally get together, while Hou Yuet marries Wing Ka. In a scene taking place four years in the future, it is revealed that Wing Ka is alive in his late thirties. Yan Hung, now living abroad in New Zealand, refuses to take her half of Moonlight Bakery's shares and approves of So Sum and Wing Ho's relationship.
