Marrying The Fake Invalid Dragon Lord

“After my own father shattered my Dragon Core and chained me in a rotting dungeon for a full year, my half-sister finally came to visit. Wearing the majestic gown of a Dragon Queen, she forced the "Soul's Extinction" poison down my throat. "Still waiting for someone to save you? Your twelve-year-old brother was beaten into a pile of mashed flesh at the palace gates! And your fiercely loyal guard captain? Shot through by heavy crossbows and fed to the rogue drakes!" Listening to her gloat about how she stole my beloved Crown Prince and turned my entire family against me, I choked on black blood, letting out a bestial screech of pure despair. I swore that if there was a next life, I would drag them all to hell and make them beg for death! When I opened my eyes again, I was back at age eighteen. Outside the door, my sister was leading a crowd of nobles to "catch" me in a scandalous affair with a drunken intruder. Looking at the disgusting man lunging at me, I didn't cower and beg like in my past life. Instead, I grabbed a heavy iron poker from the hearth and mercilessly shattered his kneecaps! When the door was violently pushed open, everyone gasped. I was stepping on the intruder's bloody face. Right then and there, I slapped my hypocritical sister across the face and tore my betrothal contract to pieces, throwing it at my scum fiancé. Since my father saw me as a disgrace, fine. I severed all ties with the family, took my mother's loyalists, and willingly took my sister's place to marry Drake Spencer-a crippled, bloodthirsty young lord with only days left to live. Everyone eagerly waited for the news of my brutal death on my wedding night. But when the bedroom doors closed, I pinched the chin of my supposedly paralyzed husband and whispered in his ear with a cold sneer: "Was that a good show, my lord?" In the next second, the "paralyzed" man instantly pinned me down. His golden eyes, like an awakening primordial dragon, narrowed dangerously in the dark as his husky voice brought a crushing pressure: "My lady, knowing too much... can be fatal."”
