Goodbye, My King of Atlantis

Mermaid princess Lyra, betrayed and slapped by her fiancé, the Sea King Dorian, resolves to erase every memory of him within seven days. After Dorian turns a blind eye to the vicious female supporting character Vivienne destroying Lyra's late mother's wedding dress and even self-harming to frame her, Lyra completely loses all hope for their relationship. When the wedding oath ceremony concludes, Lyra's memory pearl turns entirely black. Faced with Dorian's belated kneeling proposal, she coldly asks, "Who are you?" Dorian, upon learning the truth, frantically tries to win her back, but Lyra has already turned into a human and lives happily with another person on land, leaving Dorian to endure the torment of eternal remorse in the deep sea.
