A love that entangled the vicissitudes of life.
Just because of hatred, there is a gap between them.
I can't let go, you and I are intertwined in love and hate.
If there hadn't been that past event,
Will you play the song "Eternal Regret" with me again?
But, there is no if.
Duan Yaxiao and Nihong are brother and sister. They have lived in the Peach Blossom Garden since they were young. Little did they know that their mother had already died for the country. However, due to various reasons, the Chu Shang Kingdom judged her to be a traitor, so they have been looking for and killing her children, leaving no traitors. Duan Yaxiao and Nihong have been living in seclusion in the mountains. The passage of sixteen years has made Chu Shangguo gradually forget these two "rebellious sons", and the king has become more corrupt, addicted to beauty and pleasure. The corrupt Chu Shang Kingdom is about to perish. At this time, the unknowing Duan Yaxiao and Nihong come out of the mountain. What they face will be the dark and bottomless love and hatred, a huge world. How should they face it when they have never seen the world? And who is the master who has concealed his identity for many years?
