Born from the legendary love between humans and dragons, the hybrid race known as Drik looks human but carries the strength, regeneration, and instinct of dragons, including a powerful heat cycle that returns again and again. Among them, Sieric Lorence stands apart, his bloodline so rich with dragon power that he has become an unrivaled knight. Sent by royal command to rescue researchers trapped in ancient ruins, Sieric crosses paths with Jahid, a petty thief trying to steal his sword, a blade forged from dragon bones. As Sieric prepares to punish him, fate strikes cruelly. His heat arrives unexpectedly, and without suppressants, he is left dangerously vulnerable. Noticing his condition, Jahid makes a bold offer. As a fellow Drik, he can help Sieric endure the heat, but only in exchange for his freedom. In the heart of forgotten ruins, surrounded by danger and desire, a risky bargain is struck that could change both of their fates forever.
