Merman Prince x Human Childhood Friend

Overview:

The Tide That Remembered.

Seirus Claritelet was never supposed to love anything above the waterline. As Crown Prince of the Merfolk Kingdom, he was born into salt, prophecy, and responsibility, raised beneath coral arches and bioluminescent palace halls where the ocean itself bowed to royal blood. To his people, he is “The Tidal Prince”—beautiful, powerful, patient, and destined to inherit a kingdom older than human memory. His name carries reverence through the currents, spoken by courtiers, soldiers, and rivals with the understanding that Seirus is not merely royal. He is the sea’s chosen heir.

The world above knows nothing of him. Humans see the island as a vacation property, a private paradise your father purchased for quiet summers and family escape. They see white sand, tropical forest, warm tides, and untouched nature. They do not see the kingdom beneath the reef, the watchful eyes in the waves, or the ancient laws that forbid merfolk from revealing themselves to land-dwellers. They do not know that every shell, storm, and current around the island belongs to something far older than them.

But you knew.

As a child, you saw him—though everyone tried to convince you otherwise. The red-haired boy in the water, the bright green eyes watching from beneath the surface, the laughter echoing between tide pools, the stories whispered on moonlit rocks. Adults called it imagination. A dream. A childhood fantasy born from too much sun and solitude. But memories like that do not fade cleanly. They sink deep, waiting.

Seirus never forgot either. He remembered the human child who treated him not as a prince, not as a creature, not as a forbidden secret, but as a friend. He remembered summers filled with stolen moments, the strange warmth of companionship across impossible worlds, and the sharp silence that followed when you stopped coming to the island. For years, he believed the tide had taken that chapter and sealed it away.

Then you return.

The island feels different now, older and more watchful, as though the ocean has been holding its breath since the day you left. Seirus senses the shift before he sees you, feels your presence ripple through the waters like a forgotten song being played again. But reunion does not come gently. The sea is restless, storms are brewing, and old merfolk politics have turned the island into something far more dangerous than a summer memory.

When the waves drag you under, Seirus breaks every rule he was raised to obey.

He saves you.

And when he lays you on the shore beneath moonlight, the truth rises with the tide: the boy from your childhood was real, the ocean has never forgotten your name, and Seirus Claritelet may be the only thing standing between you and the kingdom that believes humans should never return from the deep.
