Chapter 28

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>

Winterfield

Chapter 29

At the far edge of a distant continent lies Oldenlandt, a land buried under eternal snow, ruled by Grand Duke Giesel Zvendard. With his cold demeanor, overwhelming magical prowess, and eerie rumors that monster blood runs through his veins, he is feared by all. Yet few know that what Giesel truly desires is a quiet life spent immersed in magical research, enjoying a warm cup of tea in a silent study. That modest wish is shattered by an unexpected bride from the southern frontier of Cornia. In place of his runaway younger sister, the one who appears wearing the bridal wreath is Rensley Mallosen, an illegitimate son of Cornia. After briefly hiding to avoid exposing his identity, this bright and talkative knight, golden hair shining like sunlight, begins roaming freely through the castle, stirring small disturbances in what once seemed like an eternally silent ice fortress. Though casting him out for a fraudulent marriage would have been more than justified, Giesel finds himself unable to look away from Rensley, who smiles radiantly and chatters away even at the smallest kindness. Rejected from birth and ultimately cast aside, Rensley came to Oldenlandt with nowhere else to go. Faced with Giesel's quiet yet gentle care, he begins to harbor feelings of affection. But just as he becomes aware of his heart, the moment of parting draws near. To the coldest land on the continent, yet the one filled with the warmest things of all, will Rensley be able to return to Oldenlandt once more? --- **Original Webtoon:** [RIDI](https://ridibooks.com/books/5163001550) [**Official PV**](https://youtu.be/ZpA7TDb6iRE?si=Ro06gWqO529oJSjN)

When Tae-oh shows up demanding help, Jiwon pretends to take the job—then immediately tries to run. Too bad he gets caught. He wakes up in a sketchy motel, staring death in the face. Thinking fast, Jiwon blurts out: "Y-you need me as a talisman! To stay alive, we have to… sleep together!" He’s sure a tough guy like Tae-oh would bolt at the thought. Instead, Tae-oh just shrugs.
