The Return of the Abyss PrincessEpisode 49

Kalya, the true princess of the Coral Sea, was swapped by her maid Melara twenty years ago and suffered harsh abuse in the lower world. After returning to the Coral Castle, she faces the fake princess Marella, who stole her identity, and her biased elder brother Egil. Hiding her wits behind a gentle facade, she strikes back step by step. She takes Marella’s fiancé, the merman prince Oseros, exposes treasonous leaks, seizes commercial power, and finally ascends as the ruler of the Coral Sea.
