The Prince Consort Isn't After Power

In my previous life, my cousin and I married on the same day. He married the beautiful, radiant princess, while I married the fierce, formidable daughter of a wealthy merchant. Now I’ve returned to the day the emperor arranged our marriages, and my cousin is fighting to marry the very coarse merchant’s daughter he once looked down on. In his previous life, the princess had trampled on and humiliated him, and he died in a dark, airless prison. I, meanwhile, had a vast fortune and lived a carefree, independent life. This time, he gleefully cursed me, saying I’d die without an ounce of dignity at the princess’s hands. But he had no idea that this time, I’d live even better than before.
