Thomas Lee (Lin Baoyi/Chen Jianlang) was born in poverty. When he was young, he worked hard to earn money for his mother's (Zhang Huiyi) medical expenses. He met Sammy Fong Siu-wei (Zhou Jiayi/Tan Shanyan), a girl working in a tea restaurant, and they became good friends. The owner of the tea restaurant (Paul Chun/Ai Wei) assigned Thomas to Belgium to smuggle luxury watches. Due to a serious mistake, he stayed in Belgium for 20 years and met Judy (Li Sihan), his confidante who had been through thick and thin with him. Four years ago, Thomas returned to Hong Kong to open a restaurant with Sammy and met Joyce Ho (Wei Shiya/Yang Siyong) whom he met in Belgium. The two hit it off and soon got together. Thomas later discovered that Joyce had been dating a man named Wu Qiyuan (Chan Hanyan/Huang Dingqian) for eight years and had a son (Chen Jiaqi) with a married woman named Liang Shuyuan Catherine (Ng Wing-wai). The relationship between the six people is complicated and confusing. Fate made their lives intertwine, they met, got to know each other, got along with each other, separated and met again, and the love and hate that entangled them for a lifetime ended up with a sigh.
