"My father has been an official for twenty years, and in the end he was given a glass of poisonous wine. Although this father gave birth to me and did not raise me, at least he taught me one truth in his life. Accompanying the emperor is like accompanying a tiger. At least I, Qing Chang'an, will not have any unnecessary involvement with the imperial court in this life. Even if I am related to the imperial court, I will never sacrifice my life for him."
This is the heroine.
"Chang'an, I promise you Chang'an for the rest of your life, can you follow me?"
This is the male protagonist.
