Dendam sang putri duyung

Orphan mermaid Coral Maris sneaks into sea witch Nerissa’s cliff mansion as a maid to avenge her mother’s murder and retrieve stolen family heritage within seven days. She soon finds Nerissa’s husband Kai, a trapped noble poisoned by his wife, shares her hatred. The two form a secret alliance, plotting to expose Nerissa’s crimes: poisoning the old king, stealing mermaid relics, and dark abyss magic. With help from loyal servants and sea allies, they unveil Nerissa’s evil deeds at her birthday gala. After a dramatic tribunal, Nerissa breaks free with her clan’s aid, unleashing forbidden witch power. Coral, as the last mermaid priestess, defeats her, dismantling the villain’s illegal weapon lab. Finally, Coral heals the ocean’s wounds, secures a council seat, and accepts Kai’s proposal, turning revenge into a new peaceful future.
