Chapter 34

364

I found myself back in that horrific spring. The season when the countess drained my blood in the name of a ritual, and when I suffered endless abuse without even knowing my mother had already died. In my previous life, the person who pulled me out of that living hell was the cursed Grand Duke, Kallian Orpheus. Our contract marriage began with a simple bargain: he would save me from the count’s estate, and in return, I would ease the madness that tormented him. What began as a calculated arrangement slowly became something more. I fell in love with him. Those days were the happiest of my life, even though the countess’ curse eventually led me to a miserable end. If I want to uncover the truth behind my mother’s death and my own, I must escape that estate once again. And as an illegitimate child with no power of her own, I have only one choice. "Just one more time… may I lean on you?" Falling in love with you was never part of the plan. At least, not in this life. _Source: <a href="https://page.kakao.com/content/69291932" target="_blank" rel="noopener noreferrer">Kakao Page</a>, translated_ Original Webtoon: R19: <a href="https://page.kakao.com/content/69291932" target="_blank" rel="noopener noreferrer">KakaoPage</a>, <a href="https://webtoon.kakao.com/content/%EC%A0%80%EC%A3%BC%EB%B0%9B%EC%9D%80-%EB%8C%80%EA%B3%B5%EC%9D%98-%EC%95%84%EB%82%B4%EA%B0%80-%EB%90%98%EC%97%88%EB%8B%A4-19%EC%84%B8-%EC%99%84%EC%A0%84%ED%8C%90/4871" target="_blank" rel="noopener noreferrer">Daum</a> R15: <a href="https://page.kakao.com/content/69291938" target="_blank" rel="noopener noreferrer">KakaoPage</a>
