Heartbeat Concerto

There are two types of people that heart surgery nurse Lin Xue doesn't want to deal with in her life: police, and people more stubborn than police. When Lu Jun, deputy captain of criminal investigation, burst into her emergency room with a gunshot wound, the two kinds of people became one. He handled the case vigorously and resolutely, but he couldn't see why there was resistance to the police badge hidden in her eyes; she sutured the wounds calmly and professionally, but she couldn't avoid the truth that was approaching step by step when he pursued the old case. From bizarre hospital thefts to dangerous cross-border rescue situations, when medical ethics collide with police missions, tenderness and hardness confront each other repeatedly on the edge of life and death. It wasn't until the dusty case of death in the line of duty was reopened that she discovered that the policeman who always wanted to protect everyone was the heartbeat she wanted to protect the most. The promise he made with the ring was: "I can't come back safely every time, but the end of every adventure is to return to you."
