Revenge: Exchanging Lives With My Sister

My sister and I were both subjected to a secret family potion that altered our constitutions.

My sister was transformed into a woman cursed to need male companionship to survive.

I, on the other hand, became someone who could conceive just by being touched by a man.

After this transformation, I was sent into the royal court to vie for favor, yet I never won the emperor's affection and ultimately met a tragic end during pregnancy due to political scheming within the royal court.
