After my elder sister swapped our marriages, I vowed to put the short-lived prince on the throne as Crown Prince...
[Dual Rebirth + Marriage Swap and Substitution + Face-Slapping Revenge + Sweet Romance]
In my past life, my elder sister married the second prince, a man as cold as ice and destined for a short life, and died suddenly.
After being reborn, my elder sister stole my marriage match, not knowing she'd leapt into an abyss with no bottom.
Elder Sister: "Little sister, becoming the second prince's consort is a blessing you earned in your past life!"
Me, a lowly concubine-born girl with neither power nor influence, have no choice but to accept this blessing.
Except...
In this life, my elder sister will never have the loving marriage she longs for, the kind everyone envies.
And I've decided to defy fate, save the second prince, and help him claim the position of Crown Prince!
But the man who was cold as ice to my elder sister in his past life now treasures me above all else. "Youran, only I can give you what you want, even if it's this entire realm!"
My mother-in-law, Consort Shu, treats me like her own daughter and fiercely has my back. "Don't be afraid, Youran! Who in this realm could be more powerful than your imperial father?"
My wicked elder sister was so enraged that she went mad and spat blood, then tried to drag me down to hell with her.
No matter. My backer is as mighty as the heavens. If you're not scared of me, then I'll admit defeat!
