Brothers Without a Tomorrow

To secure an alliance between the northern kingdom of Leracal and the southern realm of Arnata, the countries' royal families agree to a political marriage. Tei, known across the frozen battlefields as the most fearsome warrior and monster hunter, volunteers himself as the kingdom's hostage, trading his life as a warrior for that of a bride. In Arnata, Tei finds not the hostility he anticipated but the calm, steady gaze of Shuraka, the young crown prince destined to become both his spouse and future Padisha of the empire. For Shuraka to claim the throne, however, he must survive an uprising that threatens the kingdom—once that forces him to draw the blood of his own brothers. Moved by the courage and gentle integrity of his betrothed, Tei pledges to protect him at any cost...and in the quiet hours of a white night, two hearts caught between loyalty and longing begin to bloom.

Blossoms of the White Night

백야의 꽃길

Tomobashi, Kametsu

Aka no Nitamame

In a matriarchal world where women dominate and men are treated as lesser beings, Kureto was cast aside at birth for the sin of being born male. He scraped by as an orphan, unwanted and powerless—until the day his unique skill awakened. A "supreme virility" skill that strengthens him with every act shared with a woman.

Under the guise of "training" with his dorm caretaker, Kureto masters his newfound power, achieving strength no man should possess. When he's accepted into the elite Knight Academy—a school meant for noble-born women—he sees a chance to change his fate. To become an honorable knight, to reclaim his dignity, Kureto will fight—both in the arena and between the sheets—against the very women who once looked down on him.

Tiger shifter Yongwoo is an actor within the shifter world. At a filming set, he happens to rescue a black cat who'd been abused for being bad luck, and ends up bringing it home to raise it.

And with his wallet and valuables whisked off, no less! The media erupts with reports that accuse Yongwoo of abandoning his rescue pet. In order to quell the public outrage, Yongwoo offers to live along with Haedong, the very same cat shifter who'd pretended to be a cat and tricked him all along.

Devoured: The Serpent and the Pomegranate

석류를 삼킨 뱀

Haga

I opened my eyes underwater, then found myself in a dazzling palace straight out of a historical fantasy. There is no doubt about it, I have been isekai'd right into the world of a novel. And lucky for me, it is even the genre I loved the most, so I know all the rules. Or so I thought. Because in this world, instead of gaining power through intimate encounters, anyone who loses their virginity becomes cursed. Yes, cursed. In a supposed mature fantasy. How does that even make sense? While I am still trying to wrap my head around this ridiculous twist, I receive my main mission: help the story's second male lead achieve his destined romance. Avoid curses, dodge questionable situations, fix the love plot, survive the chaos, all with my purity intact. Can I possibly complete this mission without destroying the entire story, or myself, first?
