But after high school, the promise she made in the past came to nothing, and she calmly chose to leave without crying or entangled. With the help of the Pei family, she went south to the south of the Yangtze River with her medical skills, stayed in a house to take care of the sick and young children, and won respect for her kindness and benevolence.

After going through ups and downs, Gu Tong finally gained a sincere love and started a new life of his own.
