A princess of a country doesn't like women's clothing, but she likes to wear men's clothing and hang out in the land of fireworks, drinking and having fun with rich men. After being carefree for sixteen years, she found out that her twin brother was working as a spy in another country. Due to his sudden disappearance, she had no choice but to wear the military uniform for her brother, join the army on his behalf, and continue her career as a spy.
Unexpectedly, the general of the other country's country returned to the court. King Dian Yun, known as the "Rakshasa", was so cruel and cruel that she would assassinate anyone he could not afford to offend. The King of Dian returned to the court with only one purpose, to get back his royal power, but he was interfered with in every possible way by this little girl...
From the moment he returned to the court, everything seemed like a puppet being pulled by strings. Everything seemed to be deliberately arranged by someone. He didn't believe that just this little girl could control it. There must be a real murderer behind the scenes. Who was he? What is the purpose?
In the intertwining of love and hate... He actually became her father-killing enemy.
"Please bless me to sleep here forever, otherwise you will never have peace!"
"I love the country and the people, and I love you even more!"
Purpose: I don't want the people to be displaced and have no life. I want to re-establish a paradise where the people can talk and laugh.
