Double Agent Princess

I always think that men's revenge on the battlefield is the most cruel and terrifying. In fact, women's revenge is not inferior to men at all, and is even more cruel and terrifying. I am the second princess of the Yan Kingdom. My elder sister said that I wanted to restore the country, but I just wanted to live a good life. However, my elder sister pushed me to the edge of restoration time and time again. From then on, I lived a life of intrigue in the palace.
