His name was Lu Zheng, and he was the "Brother Zheng" who was frightened by the underground world in Nancheng. He was also the secret pain that Su Yan had engraved in her heart for ten years.
Ten years ago, an accident caused the family to collapse, and he regarded her as a sworn enemy; ten years later, during a surgery, he became her "special patient" and said, "Only you can cure it." She fell again.
He mocked her to the extreme, using indifference to disguise vulnerability, and using spikes to guard against sincerity; she pressed on to him step by step, protecting life with medical skills, and melting ice with deep love. But when the secrets of the past are revealed layer by layer, and when the flames of revenge and the desire to stay together fiercely collide, they realize that they have already been destined to be separated from each other.
"Su Yan, don't force me."
"Lu Zheng, I won't force you, I'll wait for you - wait for you to let go of your hatred, wait for you to run towards me."
From blood feud to life and death dependence, they redeem each other in the light of swords and struggle forward on the edge of love and hate. On the thorns, flowers will eventually bloom, and this sadomasochism that spans ten years will finally end in the name of love.
