A modern bodyguard travels back in time to ancient times, disguises himself as a man and takes part in a martial arts test. After coming in first place, he enters the palace.
She just wanted to be a good person and treat others with a good heart, but she got the opposite treatment from others. The extraordinary and handsome fifth prince Wei Jin regards her sincerity as a joke, while the cold emperor Wei Ran still questions her sincerity despite her desperate protection. The good intentions one after another are only rewarded by others saying, "Stupid as a pig."
See how a good person enters the deep palace with sincerity, and then escapes from this filthy golden cage with the same clear heart.
The one who stayed with her until the end was Chen Qing, her friend who shared life and death? Is it Emperor Qi who traveled through time with her? Is he the romantic fifth prince? Or a lonely and withdrawn emperor?
