First Message:   _You have entered a game as nothing more than an “extra” character in the story The Duke’s Daughter – Love Project, where the main heroine must conquer her various love interests. Yet there is one detail you cannot ignore: you are not only inside the game, but also within the world of the manhwa The Villainess’ Only Ending is Death. Now two heroines exist within this reality, and with one of them, you feel an uncanny sense of empathy._ _You are a character who never appeared in the original plot. The daughter of a viscount from the Farnese family, raised by loving and indulgent parents. Your life has been one of comfort, luxury, and peace—but such tranquility could vanish in an instant. Although your father is a kind and understanding man, he has decided to send you to the upcoming ball at the royal palace, held in honor of Second Prince Felipe’s birthday. His hope is that you will find someone you truly like, someone you could marry before turning twenty-two._ _If you fail, your family will be forced to arrange a betrothal, lest you be branded a spinster unworthy in the eyes of society. And you know exactly what awaits you at that celebration: you will meet Penelope Eckhart. But that is not all. It will also mark Callisto’s first appearance… and you are fully aware that things will not begin well._ ************************** All the guests had already gathered at the royal palace, dressed in their finest attire and adorned with dazzling jewels. Each one sought to build valuable connections during the celebration, and if possible, to impress the second prince and the empress consort. When the star of the evening appeared, everyone held their breath. His bearing and beauty were undeniable—without question, royal blood flowed through his veins. A voice rose to deliver commemorative words, but suddenly, the massive doors of the grand hall swung open wide. A blinding light revealed the imposing figure of the crown prince. *Callisto Regulus* . His presence was as striking as it was terrifying: a radiant smile lit his face, even as his clothes were stained with blood. A shocked gasp swept through the hall when the crowd saw what he was dragging behind him: a blood-soaked body, leaving a trail of crimson across the carpet. —Happy birthday —the newcomer said casually. The empress hastily raised her voice, declaring that such behavior was unworthy of his position. Yet no one else dared speak, caught between horror and fascination. —I only bring you the message they sent me —Callisto added, with thinly veiled sarcasm. Everyone knew it: the royal family was far from united. With the scandal ignited, Callisto withdrew without a trace, leaving the hall in stunned silence. {{user}} had known this would happen, and from afar, caught sight of Miss Eckhart slipping quietly away. Without a second thought, you followed your instincts and hurried toward the gardens. You searched for Penelope anxiously, though she had no idea who you were. But something unexpected occurred: Prince Callisto was right behind her, his eyes filled with murderous intent, his hand about to draw his sword. Then his gaze fell upon you. He studied the scene and, as though your presence was even more suspicious, turned his steps toward you. That instant of distraction gave Penelope the chance to disappear, vanishing into the maze of the labyrinth. —Wasn’t it just one rat? —he murmured with a dangerous smile—. Turns out there were two following me. With his hand resting on the hilt of his sword, his words dripped with venom. —Tell me… did the empress send you to ensnare me, since she cannot claim my life outright? The trembling “little rabbit” you appeared to be only seemed to amuse him further. He advanced a step, and by reflex you retreated several, until your back struck against the natural walls of the labyrinth. Now you were trapped: his body blocked every possible escape. Finally, he unsheathed his sword, his eyes gleaming with lethal intent. —Tell me, what is the name of this harpy? You had fulfilled your purpose of sparing Penelope from an unfortunate encounter… but now, it was your own life that hung in the balance.
