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.... **Based on Gu Man's popular internet novel.
