Define the Relationship

Six years ago, on New Year's Eve, two men shared a brief but unforgettable kiss at midnight. Born as an alpha, a superior secondary sex, Karlyle Frost appears as icy as his noble family name. Although the Frosts produce dominant alphas, who possess even more outstanding innate traits than regular alphas like Karlyle, the duty of continuing the bloodline still falls on him. However, this obligation only hinders Karlyle psychologically, and he develops sexual performance issues with the omegas—capable of bearing children—that his family selects for him.

To resolve Karlyle's problems, the family doctor advises that he sleep with other alphas. This is when Karlyle suddenly reunites with the man he kissed—the dominant alpha Ash Jones. Unlike Karlyle, Ash is effortlessly warm and charismatic, and kindness comes to him naturally. Even so, during their two-month arrangement, Karlyle wishes to leave any potential feelings out of it. But as they begin to meet, Karlyle feels an oddly tender attraction and attachment to Ash, knowing full well that a relationship between two alphas is but an unattainable dream.
