My Fiancé Slept with His Partner on Our Wedding Day

Human heiress Aurelia Sterling backs dragon‑shifter Cassian to be New York’s Dragon King and agrees to marry him. On their wedding day, Cassian cheats with snake‑shifter Selene in a copied wedding dress, demanding Aurelia tolerate her for reputations. Furious, Aurelia cuts his funding, strips his title and ends the engagement, rescuing injured deposed wolf royal Kael from deadly underground fights. Disgraced and abandoned by families, Cassian marries pregnant Selene but deserts her. She dies in childbirth, and Cassian’s corpse turns up later. Kael defeats the wealth‑dependent Cassian, then rejects his northern throne at a gala to confess his love for Aurelia.
