When Cheng Changan was seven years old, his father brought back an orphan who was a busboy in a restaurant back to his hometown.
When they first met, he was disgusted with the boy who replaced his father's gaze, and deliberately poured hot medicinal soup on the other's hands.
Returning home, he silently wiped the burns on the back of his hands, but Cheng Changan became even more furious because of his silence.
After ten years of companionship, Cheng Changan was shocked to realize that he could no longer live without him when he returned to his hometown to block the poisonous arrow.
After he ascended the throne, he knelt in front of his hometown door all night, and finally got her to return to the palace.
When the enemy army broke through the imperial city, he returned home and used his body to block the fatal arrow for him.
"Your Highness, leave quickly... This time, my hometown really can't protect you."
Cheng Changan hugged his increasingly cold body and understood for the first time what it meant to be heartbroken.
It turns out that the last gift left for him when he returned to his hometown was to learn to cry.
The stubborn and lonely prince Cheng Changan's life changed drastically when the orphan boy brought back by his father to serve as a cadet returned to his hometown. From hostility and bullying, to being shocked by the other party's kindness in return, to the youthful friendship that depends on each other in the palace, until it develops into a profound bond that transcends the monarch and his subjects. This friendship has experienced suspicion, frame-up, life and death in the whirlpool of power. Cheng Changan grew up from a self-centered child who struggled with loss and pain to an emperor who was burdened with the country. In the end, he lost the light that illuminated his life forever - returning to his hometown. Returning to his hometown explains what silent protection is with a lifetime of loyalty, forbearance and sacrifice, and finally fulfills his promise with his life.
Purpose: To explore the struggle, purity and destruction of individual emotions (family, friendship, love) in the midst of supreme power and the shackles of the palace; to show how a "bad boy" completes the redemption and transformation of the soul in love and loss, at the cost of eternal regret and heartache.
