In the winter of his third year of middle school, after an unexpected accident struck his family, Ihyun moved to his grandfather's house in a small fishing village, where he graduated from high school. One rainy night, he leaves the village secretly with his only friend, his cousin Leehan, and his girlfriend, Morae, leaving his father behind. Becoming a fugitive, he works part-time at a moving company. Ihyun reunites with a past connection and helps with the work at the gallery 'Phantom'. There, he encounters the world of golden alphas and golden omegas, which he thought he would never be involved in. Despite the humiliating rumors that he is a 'blue-eyed golden alpha who sells paintings by seducing people with pheromones,' the CEO of 'Phantom' has quickly established the gallery's position with unconventional moves. He treats Ihyun, who is practically an outsider, with caution and coldness... ―Part-timer. ―Am I the same as that guy? ―There's no one, no one at all. Ihyun feels his suppressed emotions stirring at the CEO's indifferent words directed at him. "About that, are you really not an omega?" The CEO confuses Ihyun by asking and talking about him when Ihyun is not around, seemingly indifferent, but he can't quite accept the fact that Ihyun is a beta... "Your perfume... It's very unique." "You like my perfume, don't you?" What about their past and future intertwined with paintings and pheromones?
