Main plot (highlights):
I was born as a "sacred vessel" to sacrifice for the empire. I was raised in a deep palace, waiting for the fourth prince Xiao Lin, whom I had a crush on, to personally deliver to the altar for sacrifice. He was humiliating and cruel to me in every possible way, leaving me to die in despair. However, at the last moment of the sacrifice, he turned his sword and killed his biggest political enemy, the prince, with thunderous force. It turns out that this sacrifice was a shocking plot set up by him, and I was the only love he wanted to save from death even though he would bear eternal infamy. From a sacrifice to a beloved person, the person who was once the most ruthless to me now spends his whole life repenting and pampering me.
