Emergency physician **Yan Xia** and director of cardiac surgery **Li Shen** are childhood sweethearts who have been separated for twenty years.
When we met again after a long absence, he was the well-known "Iceberg Doctor" in the hospital, rigorous and restrained; she was the backbone of the prosperous emergency department, enthusiastic and courageous.
The two hearts got closer again in the giant white tower, but they faced family resistance, professional pressure and knots that had been hidden for many years.
**When the stethoscope encounters a rapid heartbeat, when the operating light illuminates the old promise——**
Li Shen kept every childhood photo, remembered every word she casually said, and even learned to make sweet and sour pork ribs for her because she never forgot about it when she had a fever.
Yan Xia discovered that the boy who was punished by kneeling down to deliver porridge to her would still show up as soon as she was injured and would not hesitate to protect her with his body when danger came.
**"I wanted to protect you twenty years ago, and I still want to protect you now."**
From passing each other in the hospital corridor to affectionate confessions under the stars;
From the ambiguity of testing each other, to working together to face rumors and challenges;
Their love is like the beating of the heart, stable and eternal, like the trajectory of the starry sky, already destined to reunite.
"Li Shen, your heart is beating so fast."
"Because it's you."
