I took the blame for my wet nurse's daughter and spent three years enslaved in the laundry bureau. When my sentence ended and I returned home, I found that my family had accepted her as their real daughter, taking away my title as a princess, my betrothal, and their affection. They made me sleep in the stable and serve as a foot washer. On my birthday, they even planned to drive me out. Only then did I realize that their supposed “amnesia” had all been a lie. Three years of hardship and my family's deliberate cruelty had left me heartbroken. Just then, an imperial decree called for a marriage alliance, so I volunteered to go in the princess's place and travel far to the northern frontier.
