Bound to the Duke on My Ex-Fiancé's NightEpisode 9

Synopsis

Elin, heir to a dying noble house, breaks off his engagement to an abusive fiancé and awakens a forbidden Purifying Flame. He seeks refuge with Duke Cedric—the realm's most feared sorcerer and his ex-fiancé's uncle—and their soul-bound contract slowly turns into something deeper. When a dragon-born army demands their combined fire to awaken a sleeping god, they must descend into the Dragon Bone Abyss and fuse their opposing flames—or watch the kingdom burn.
