Zhu Jiaxi and Zhou Yanchi were childhood sweethearts who grew up next to each other. Zhou Yanchi, less than two years his senior, appeared aloof, but his protectiveness was a habit. From 1997 to 2007, he raised his little clingy girl, taking her to and from school, raising her ducklings, and falling asleep to her chirping in his ear when her parents were away. When Zhu Jiaxi was ten, she had a younger brother, inevitably diverting her mother's attention. This led to her experiencing her first major setback, and it was Zhou Yanchi who supported her through this difficult time. However, Zhou Yanchi's father's business was defrauded and bankrupted, forcing him and his mother to relocate. The family upheaval forced him to break his promise to Zhu Jiaxi, and the two entered a five-year separation without any communication.
