In a rigid dragon hierarchy where bloodline decides all, Evelina, born to a wingless low-tier clan, is tricked into marrying Cassian, heir of a supreme pure-blood line. Cassian suffers from a terminal Berserk Dragon Curse and shows her no love. For five years she hides her gift as a perfumer, enduring his cold violence, her son's disdain, and the endless scheming of Octavia, an ambitious pure-blood heiress. After a near-fatal accident leaves her brain damaged, Evelina feigns amnesia, shatters her docile mask, and demands the dragon pact be dissolved. Veiled and anonymous, she sells Dragon's Breath incense that can cure the pure-blood curse, becoming the realm's most sought-after legend. Cassian, tormented by the curse, hunts for this mysterious perfumer—meeting her again and again without ever recognizing that his salvation is the wife he neglected. When her identity is exposed, he learns Octavia orchestrated everything, and that he wronged Evelina for five years. Now holding unique power, she decides her own fate and love.
