He is the sharpest scalpel in thoracic surgery; she is the calmest guardian in anesthesiology.
Lin Shen, a gifted lead surgeon in thoracic surgery, is known for his precision and decisiveness. But in the emergency room, he meets his most difficult opponent: Gu Qing, one of the city's top anesthesiologists. Calm and professional, she never hesitates to question his surgical plans. From their very first operation, they clash head-on, neither willing to give an inch.
An aortic dissection surgery binds their fates tightly together. At the operating table, he is the surgeon holding life and death in his hands, while she is the anesthesiologist guarding the heartbeat. Away from it, they are each other's toughest rivals and most perfectly attuned partners.
As crises pile up and life hangs by a thread, they gradually realize that they are not only a perfect professional match, but also the only ones who resonate with each other deep in their souls. From enemies to lovers, from confrontation to standing together, they write a legend of blades and heartbeats beneath the surgical lights.
