The Emperor's Unparalleled Daughter

I have loved Gu Yan for ten years, but he has always been distant from me. It wasn't until the day when King Nan'an asked to marry his cousin that Gu Yan finally agreed to marry me. The imperial brother personally arranged marriage for me and Gu Yan, and we got married on the same day as my cousin. I put down my pretensions and learned about housekeeping and rules, just to prepare myself for being a housewife. But on the wedding day, I discovered that I was not marrying my sweetheart, but the King of Nan'an who was in love with my cousin. King Nan'an was furious, thinking that I had ruined the marriage between him and his cousin, and humiliated me to death. When I was about to die, I learned that the emperor brother and Gu Yan were both the masterminds of this wrong marriage. When I opened my eyes again, I went back to the day when the royal brother proposed marriage to me and Gu Yan.
