Aria, a purebred little mermaid with healing water magic, rescued Nate — a chaebol young master who had collapsed into a coma from a "deep-sea curse" — off the Long Island coast, and was brought back to the Sterling family, New York's top old-money clan. Victor, the ruthless Wall Street titan, broke all precedent and adopted her, doting on her like no other. Yet her insanely jealous socialite cousin, a vicious female doctor who forged a "Sea God Mark" to marry into wealth, and gangland assassins hidden beneath Manhattan's night — all set their claws on Aria. Faced with Old Money's arrogance and deadly conspiracies, Aria not only used her healing magic to slap down the villains again and again, but also uncovered her true identity as the Deep Sea Queen, completely shattering the chaebol family's century-old curse!
