Nereia, a pure-blood mermaid princess of Atlantis, is secretly demoted to a menial weaving maid by her father King Orin to shield her from the power-hungry Western Abyss Kingdom.
After fleeing to the mortal realm, she is rescued by poor scholar Liam. Falling deeply in love, she sheds pearl-forming tears to fund his pursuit of the greedy noblewoman Vanessa, only to be brutally exploited and nearly killed by the pair.
Recaptured and left dying in a frozen prison, Nereia is chased by a remorseful Liam, who braves the deep sea to redeem himself. He uncovers the king’s hidden paternal love and the Western Abyss’s plot to drain Nereia’s power.
After fending off the invasion together, Liam proves his devotion through a deadly trial. King Orin finally blesses their union, and the two marry in Atlantis, finding lasting happiness.
