I Died on the Night When the Emperor Established His Concubine

I am a medical woman. When I went to the mountain to collect medicine, I saved the seriously injured emperor. He fell in love with me at first sight and tried every means to marry me. For me, he dismissed all the concubines in the harem and made me the queen against all the opinions. Promise to be with me forever. But in the seventh year when I became queen, he brought the daughter of the general who ruled the country into the palace and stayed with her every day, and also gave her the phoenix hairpin that belonged to the queen. I turned around and wrote a letter to my master. "Master, you are right. There are many ruthless men in the world, especially emperors. Three days later, I will fake my death and leave the palace. From then on, I will always be by your side and never leave again."
