Big conglomerate president Feng Teng has a younger sister, with a very rare blood type, who needs a transfusion. He finds an employee at his company named Xue Shan Shan and asks her for a blood donation. Afterwards brother and sister are rather indebted to Shan Shan, but rather than using Feng Teng's typical method of paying her off, his sister suggests sending her nutritious packed lunches so Shan Shan can recover from the blood loss and to make the thank you more personal. Shan Shan loves to eat and her enjoyment of the lunches, along with her general bright and sunny personality, slowly start melting cold Feng Teng's heart.
When Feng Teng's childhood friend, Yuan Lishu (Li Chengyuan) returns to the country, she is dismayed to discover that Feng Teng is in love with Shan Shan. She tries to compete with Shan Shan for Feng Teng's love. Together with Feng Teng's best friend, Zheng Qi (Huang Ming), the two try to separate the couple by inciting conflicts.
