After Rebirth, I Married the Prince's Brother-In-Law from My Previous Life

In my previous life, my sister-in-law dragged me to death in the fire. After rebirth, she snatched away my "dandy" husband from my previous life and pushed me into the fire pit of the East Palace with a smile. She thought she had the upper hand, but little did she know that beneath the skin of that playboy was a demon from another world, and that the prince she abandoned like a pair of shoes was the real dragon. I entered the East Palace with a smile, and did not compete for favors. I only managed the Crown Princess as a career. He needs a good wife, and I am the perfect partner. When my sister-in-law relied on "precognition" to become a goddess, I had already planned a plan to cut off her money; when she was reciting poems and making mistakes, the account books I had sorted out had already filled the national treasury. Later, she was sent to the enemy camp as a gift from her husband. She came back pregnant and killed the devil in front of me. She burst into tears and asked me why I didn't stop? I caressed the Queen's seal, looked at me as the only emperor beside me, and smiled to answer my questions: "Sister, the queen is a partner and a CEO. Who wants to fall in love with the boss? With all this wealth and sincerity, you made the wrong choice from the beginning."
