The One-Night Stand with the Insatiable Count Wasn’t Just a Dream! I found myself transmigrated into the body of the villainous mother-in-law from a novel—one who gets divorced by her Count husband for her vicious behavior, torments the future Queen, and ends up executed. Even if the plot’s cliché, I’m not about to die. Life is precious, after all. “I’ll gladly do it! That silly divorce!” I rushed to get the divorce finalized and stamped. Next comes the redemption arc, right? I greeted the female lead daughter-in-law with open arms. And finally, it’s only right to wish her the best when I leave. Since I know how the story ends, the path to becoming a conglomerate heiress is wide open. The time had come for me to shout, “Goodbye, everyone!” But then— “Mother! I love you! I can’t live without you!” Why is the daughter-in-law like this? “My lady, the purpose of the divorce reflection period is to thoroughly consider whether divorce is truly necessary.” And now even the husband seems strange? Then came the doctor’s diagnosis, the final straw that forced me to run away. **Original Novel:** [Chapters](https://series.naver.com/novel/detail.series?productNo=6631480), [Volumes](https://series.naver.com/novel/detail.series?productNo=11339970) **Original Webtoon:** R15: [Naver Series](https://series.naver.com/comic/detail.series?productNo=11253067) R19: [Naver Series](https://series.naver.com/comic/detail.series?productNo=12351995) **Official Translations:** [Japanese](https://manga.line.me/product/periodic?id=Z0003720)
