When My Ex Begged, I Was Already a Legend - Episode 19

A hidden war goddess, Inga, gives up her power to prove her love, living as a humble housewife for three years. But her husband betrays her, his family humiliates her, and she's thrown into an ice cellar to die. Her father arrives with ten thousand warriors to tear down the castle. Freed from her chains, Inga returns to the battlefield—slaying giant beasts, crushing the Undead King, and rising from "discarded wife" to the Empire's First Valkyrie. She makes everyone who once looked down on her kneel and beg.
