Xin Keyan was originally the young master of the Xin family in Ningcheng. Unexpectedly, overnight, his whole family was wronged and executed by the Holy Emperor. Xin Keyan, who was traveling, escaped by chance. From then on, he changed his name to Nineteen and entered the "disaster area" of "Xiangchengmen", a place where killers were trained. He was full of lives.
During a mission, Xin Keyan, who had disguised himself as an ordinary villager, was kidnapped into the mountains by bandits. Also arrested was His Royal Highness the Crown Prince, who was visiting privately incognito.
After being rescued, His Highness fell in love with Xiaojiu at first sight and asked for someone from Xiangcheng Gate to take him with him as a personal bodyguard.
After spending a long time together, Xin Keyan discovered that the cheap Highness in front of him was not as perverted as the rumors said.
"Your Highness, my life is low, but my love is not."
"Nineteen, you are the only one in the world that I can love."
