A True Daughter Must Avenge Herself, and the Regent Is Responsible for Delivering the Sword.

When I was three years old, my brother bought me lanterns for my cousin, so I was abducted by traffickers. By the time I returned to the capital, my cousin had replaced me as the pampered adopted daughter of the Marquis. I cured the Queen Mother's illness and was granted the title of princess. My cousin was so envious that I couldn't even eat. My father immediately confronted me and said that I was taking the credit, causing my hands and feet to be broken. I have been married to the Prince Regent since I was young, and my cousin wants to steal my marriage. My mother thought I was embarrassed and allowed my cousin to force-feed poison to me while I was bedridden. I was thrown into a mass grave with a roll of tattered straw mats. When I opened my eyes again, I went back to the day when I was named the princess.
