"You are my city camp." Mimi is a new resident of Renxin Hospital. Although she is ordinary and unnoticed, she is kind-hearted, hard-working and positive, putting patients' health first and eventually becoming an excellent doctor.

Mimi met Xing Kelei, an elite special police officer, during the emergency rescue drills organized by hospitals and police schools. They developed a good impression on each other in the process of getting along. In fact, they crossed paths two years ago. At that time, Mimi was a medical student and was accidentally involved in a jewelry robbery. Xing Kelei went deep into the tiger's den and rescued Mimi who was hijacked by gangsters.

At that time, Mimi left a deep impression on Xing Kelei, and at the same time, he also left a deep impression on Mimi. Two years later, Mimi became a resident and participated in emergency rescue training. She and Xing Kelei also met here, but Mimi didn't recognize Xing Kelei as the person who had saved her before.

As the relationship between Xing Kelei and Mimi gradually warmed up, Mimi knew that Xing Kelei was the benefactor who saved her two years ago, and they finally came together.
