Ex-husband Stole My Daughter's Cure, Regretted Knowing I'm The Elven Queen

To repay a life debt, Seraphina—the High Elven King's hidden daughter—seals her divine power and marries mortal lord Ronan. He abandons her and their newborn Iris for his first love Vanessa, who poisons the infant and steals her cure. Betrayed and broken, Seraphina returns to her father's throne, awakens as the Supreme Elven Queen, and ascends to absolute power. Ronan, now a ruined outcast, watches his kingdom crumble.
