Muju, a city brimming with fog, was created to emulate Las Vegas in Korea. Sahee, having wandered aimlessly, seeks refuge in this strange city, only to encounter Eundo, a man as cold and mysterious as the fog itself. “Shall I kill them?” “What?” “Those bastards just now. If you want, I'll take care of them.” He is a man exuding a dangerous aura, one that reminds her of the past she desperately fled. She should have pushed him away. After all, he was nothing more than the kind of thug she despised, merely wearing the guise of a benefactor. “If there’s anything you’d like to eat, I'll get it for you. Just pick something.” “Only a drink?” But Sahee couldn't comprehend the full extent of it. Like Persephone captivated by Hades, she never had a choice from the very beginning. “Because I have no intention of letting you go.” Everything had been meticulously orchestrated for her; it was an astonishing trap. <a href="https://ridibooks.com/books/5601000741" target="_blank" rel="noopener noreferrer">Original Webtoon</a>

Seo-hwa’s fiancé, Won-ui—whom she believed died five years ago—returns alive as a war hero. But instead of love, he comes back filled with hatred, declaring that he survived only to kill her. Years earlier, Seo-hwa’s father, the paranoid emperor of Songyang, allowed political schemes to destroy Won-ui’s family under false accusations of treason. Unable to save him, Seo-hwa watched helplessly as his family was executed and believed Won-ui himself had died. After the emperor’s death, Seo-hwa’s jealous brother forces her into a miserable marriage, dragging her life into ruin. Five years later, a rebellion topples the tyrant, and Won-ui returns victorious. Though he hates Seo-hwa as the daughter of the man who destroyed his family, he still cannot bring himself to kill her. Instead, he asks the new emperor to hand Seo-hwa over as a servant to his household. Now, the two former lovers—both broken by tragedy, revenge, guilt, and lingering love—are trapped in a painful relationship neither can escape.

Even If You Run Away, You Are Still Mine

Chapter 26

861

"If I keep indulging your tantrums, the sun will rise before I even get the chance to thrust inside you." Ye-in’s marriage to Tae-heon was a volatile storm of overwhelming, skin-to-skin obsession and crushing isolation. In the dark, his hunger for her was savage; he devoured her body with a desperate, rough tenderness that left her breathless, bruised, and utterly trapped beneath his weight. She mistook that blinding heat for love. She foolishly hoped they could become a real family. But outside the bedroom, reality was a frozen wasteland. Her trust was weaponized, her expectations trampled, and her dignity stripped away. She was nothing more than a convenient pawn in his cold, calculated world. When the illusion finally shatters, Ye-in realizes she is carrying a secret—a child she refuses to let inherit her living nightmare. Armed with a quiet, desperate resolve, she delivers the ultimate blow to his suffocating control: “Let’s get a divorce.” Faced with his icy disbelief and the arrogant conviction that she can never survive without his touch, Ye-in must sever the toxic bonds of her own heart. He claims she loves him. She did. But to save her child, she will endure whatever hell it takes to tear her life away from his. <a href="https://ridibooks.com/books/120061655" target="_blank" rel="noopener noreferrer">Original Novel</a> Original Webtoon: <a href="https://ridibooks.com/books/1561017321" target="_blank" rel="noopener noreferrer">Ridibooks</a>

Love:Zero

Chapter 20

817

Jiyu, a student at Astor School—an elite private all-girls academy in Manhattan’s Upper East Side—lives in the same apartment building as Hunter, who attends Alton School, the all-boys academy just across the street. However, between Hunter, who lives in the penthouse of a luxury Fifth Avenue apartment overlooking Central Park, and Jiyu, who lives in a first-floor affordable housing unit, there exists a gap as vast as the highest peak and the absolute bottom of a pyramid. Even their personalities are polar opposites: Jiyu loves to sit quietly and read books, while Hunter cannot stay still for even a single second. Showing a natural talent for tennis, Hunter begins competing in earnest in tournaments and wins every single match Jiyu attends. Because of this, Hunter becomes convinced that Jiyu is his winning good luck charm. Eventually, the turbulent storm of adolescence finds them both. Amidst all this, tragedy strikes Jiyu. With nowhere else to go, the Hamilton family takes her in, but Jiyu is relegated from being Hunter's friend to nothing more than a servant. Jiyu exploits Hunter to survive, while Hunter exploits Jiyu because of his superstition. In a tennis match, "Love" means zero. A love game is a game where one player's score is zero. Bound together in a tangled web of love and hate, the two face each other across the net, trading volleys in a love game. Who will ultimately emerge as the winner of this game?
