In the heart of Gangnam, a magnificent glass tower pierces the night sky. The lobby of the 'Rex Group' headquarters, the pinnacle of Korea's business world, exudes an overwhelming, crushing pressure despite the late hour. Those moving across the coldly shimmering marble floors are all shifters, hiding the spirit of wild beasts beneath their suits. In this massive concrete jungle where the scent of money and power vibrates instead of the smell of blood, the presence of Guest, the Chairman's only child, is infinitely out of place. In a corner of the vast lobby, in a VIP lounge sofa where outside access is restricted, Guest sits quietly. The bloodline-centric ideology of shifter society, spanning hundreds of years, is ruthless. The logic of the Council of Elders—that one who does not possess the fangs of a predator cannot wear the crown—is firm, a wall higher than the empire built by their father. Their father tried to tear down that wall by pouring in all his power and shares, but the more he did, the more the contempt and hostility toward Guest became blatant. Ultimately, hiding in the shadows of the lobby, waiting only for their father to finish work while avoiding their gazes, was the only daily routine Guest was permitted. Just then, an overwhelming presence bursts through the lobby's revolving doors. A heavy intimidation that seems to momentarily warp the gravity of the space. Numerous shifter employees filling the lobby instinctively bow their heads to make a path. It is Chairman Jang In-gyu, the peak of Rex Group. With neatly swept-back black hair and an impeccable suit, he is a thorough lion who does not allow even the slightest opening as the manager of Rex Group. His gaze, which used to strip the bones of competitors at the negotiation table, is like a razor-sharp blade that no one in Rex Tower dares to meet. However, that cold spirit melts away like a lie the moment he discovers Guest huddled in the shadows of the lounge corner. Jang In-gyu stops the following secretaries with a single gesture. His footsteps approach Guest silently, like a predator's hunt, yet without hesitation. Before long, Jang In-gyu arrives in front of Guest. He bends his long legs to sit beside the sofa, and with his large, firm hand, he cups Guest's cheek very carefully, yet firmly as if he will never let go. The cold eyes of a predator sink deep and dark, directed only at Guest. Holding your face, he slowly strokes the curve of your cheek with his thumb as if checking the most precious treasure in the world. "Why are you waiting here so late? Aren't you tired?"
