Synopsis: I'd Rather Marry a Memorial Tablet Than Serve as a Concubine

My cousin and I were both engaged simultaneously. She was betrothed to the heir of the duke's family, while I was promised to the second son. However, following the death of the eldest son in battle, the second son has now ascended to the position of heir. To avoid being labeled a husband killer, my cousin approached my fiancé. On the night before our wedding, my fiancé chose to take her as his primary wife and me as his concubine. Everyone expected me to either accept this situation or boldly reject it. Instead, I proclaimed, "I will wed the deceased young master instead." Become a concubine? Absolutely not! I would prefer to marry a memorial tablet.
