Eryx, the reddish-brown-haired Alpha, is a powerful businessman who owns multiple companies, with his two loyal men, Aren (silver-haired) and Kaor (brown-haired), leading his security forces. All three of them are between 25 and 27 years old and are werewolves capable of fully transforming into wolves. Five years ago, at a grand gala, Eryx encountered a mysterious server, and they shared a night that faded into fragmented memories. By morning, the woman had disappeared, leaving Eryx with only the memory of her long chestnut-brown hair and traces of what had happened. The woman became pregnant and fled, raising their daughter alone in a distant place. Years passed while Evelin, an omega close to Eryx, tried desperately to win his affection. Fate begins to intertwine past and present again as hidden bonds, desires, and long-buried truths resurface.
