I, Choi Kyung... No! In fact, my name is Cui Zhaoxue now, because my cheap brother-in-law from the country became emperor. In order to avoid the prophecy, I had to change my name. Fortunately, even if the name is changed, the character will remain the same. Wait... Sister is dead? What? Brother-in-law's father married her to someone else? What? Brother-in-law killed his father? What? Sent to fight? God, she can only work hard and try harder to avenge her sister. Wait... Sister is not dead? What? I want to investigate a century-old family? What? Did someone discover the bad thing I did? Also, what happened to Mr. Zhang who suddenly went crazy?
