"Ruthless on the outside but loyal on the inside, cold on the world but bowing to one person VS cold on the outside but warm on the inside, noble and self-sufficient but only willing to make an exception for one person"
Xue Ye's illegitimate son was on the verge of death, but he was rescued by the fallen prince Jiang Xin, and he swore to protect him ever since. Ten years later, he became a powerful king with a different surname. He was regarded by the world as a ruthless madman, but he was willing to surrender and become the sharpest blade and most loyal shadow of Prince Jiang Xin. And the cold and aloof prince, in the turbulent whirlpool of power and intrigue, gradually saw clearly the deep love between the king and his ministers that transcended exploitation, and finally became angry for him and stood side by side. This is an epic about ultimate protection, mutual redemption and unshakable bonds under the cold imperial power.
He is his only obsession, he is his only exception.
Purpose: Pure love without asking for anything in return
