The Alpha Marshal's Regretful Annulment

“In my past life, I drugged the Imperium's most powerful Marshal, hoping to force a marriage to save my royal family from ruin. But the cheap pheromone inducer triggered his catastrophic beast-form rampage, and my stepsister intentionally led the press to our hotel room to catch me in the act. I became the empire's biggest joke overnight. The Marshal's family crushed what was left of my reputation, and my own mother, the Queen, immediately stripped me of my royal title to save her own skin. I was locked away in a mental institution for years, drowning in millions of debt, while my stepsister took my place and everything I owned. I died alone, ridiculed and completely abandoned. Until my dying breath, I couldn't understand why my own family set me up to take the fall, or why my desperate sacrifices only earned me their absolute disgust. Opening my eyes again, I was back in that hotel room, the beastly Marshal growling in the bathroom. This time, instead of crawling to him begging for love, I grabbed a military-grade suppressant and stabbed it into his neck. Then, I sat amidst the wreckage and calmly waited for my stepsister and the reporters to burst through the door. "I am not your prey, and I am not your cure." This time, I would sever my ties with the royal family myself and use my future knowledge to make them all pay.”
