I Made a Swap with My Legitimate Sister

In my previous life, my legitimate older sister formed a bond with the young lord of the wolf clan.

I became the eleventh wife of a tailless evil serpent.

My sister thought she would enjoy unparalleled honor and prestige.

But the young lord of the wolf clan went mad and slaughtered his entire clan. My sister escaped by sheer luck, only to become a widow at a young age.

As for me, I unexpectedly won the evil serpent’s affection. He luckily obtained the dragon clan’s inheritance in a secret realm, and I became the envy of everyone as the lady of the house.

My sister went mad with jealousy and stabbed me to death at my birthday banquet.

Living a new life, my sister eagerly chose the evil serpent. “It’s my turn to enjoy the good life!”

Oh, my foolish sister.

Does she think she knows how the evil serpent got his reputation, or how his wives died?
