After I Became a Substitute Bride, the Crippled Prince Helped Me Become Empress

I took my elder sister's place and married the crippled, disfigured prince. He despised me and bullied me, making me kneel for three full hours on our wedding night. Later, when enemy troops reached the gates and no one at court dared to fight, he dragged his broken body along and led the officials in kneeling outside my palace. "Princess Consort, please, save this realm." Clad in a dragon robe, I stepped out of the hall and looked down at the man who had once ground me into the dirt. "Your Highness, you've come to the wrong person. You should address me as Your Majesty now."
