Regret It, Ex-Husband Your Powerless Wife Is the Supreme Mage!

Synopsis of Regret It, Ex-Husband Your Powerless Wife Is the Supreme Mage!: Two years ago, Caroline saved the Royal Capital from a deadly Elemental Surge, draining her own elemental core. Instead of gratitude, her fiancé Killian believed his friend Amber's lie—that Caroline stole Amber's core to fake heroism. He ripped the core from Caroline's weak body and rode away, never knowing it would slowly heal on its own—and that marrying him was Caroline's final test of his worth. For two years, Amber lived as a celebrity with the stolen core, winning fame, Killian's devotion, and even Leo, Caroline's baby dragon familiar. Everyone abandoned Caroline except Lumi, her quiet gray-and-white beast. Then Killian threw Caroline into a blizzard after Leo clawed Lumi. Her old wound flared; she passed out in the snow. Lumi refused to let her die—bursting with seven-colored magic, restoring Caroline's elemental core. They were found by Fenric, High Judge of the Elemental Council, who had secretly cared for Caroline for years. Now Caroline is entering the realm's greatest elemental tournament—to reclaim every bit of stolen glory and make every traitor pay.
