About The Mermaid Only Saves Once

When mermaid Irene sacrificed her heritage and traded for human legs to pursue Cassian, the dying billionaire heir she saved from the abyssal depths, she never imagined he would mistake a cunning impostor for his savior and brutally shatter her knees. Cast out like broken trash, Irene crawls back into the ocean, where Leon, the crown prince of the deep sea, snaps his own sacred dragon horn to forge her unbreakable new joints. As Leon unleashes an undersea crusade that annihilates Cassian's global empire, the truth finally comes to light: the lullaby within the sacred conch carries Irene's undeniable voice. Consumed by agony and remorse, Cassian crushes his own legs with the very hammer he used on her and crawls across jagged coastal rocks for days, only to be met with her chilling disdain. When vengeful hunters threaten her sanctuary, Cassian drags them down into the watery abyss in a desperate final bid for atonement. Yet the mermaid who once gave everything will never look back. Beside Leon, Irene claims her sovereign crown, trading bitter betrayal for a radiant reign in the deep sea.
