PROLOGUE. Cursed Siren
Long ago, far beneath the endless dark-blue waters of the Ocean, there existed a hidden world untouched by human eyes—a magnificent kingdom where extraordinary creatures lived among glowing coral forests and shimmering underwater cities.
They were known as sirens.
From afar, they resembled humans, possessing graceful faces, elegant figures, and voices as enchanting as music carried by the sea breeze. But beneath their waists stretched long, powerful tails covered in glistening scales that reflected every shade of the ocean—emerald green, sapphire blue, silver, and violet.
The oceans were once their paradise.
Massive whale songs echoed through underwater valleys while schools of radiant fish danced beneath beams of sunlight that pierced the water’s surface. Coral palaces stood proudly on the ocean floor like living castles carved by nature itself. Sea turtles drifted peacefully among colorful reefs, and the currents carried the sirens’ melodies through the endless waters.
For centuries, humans and sirens coexisted peacefully.
The sirens admired humanity’s curiosity and creativity, while humans respected the sea and the creatures that lived within it. Fishermen would offer songs of gratitude before sailing home with their catch, and sailors once believed that hearing a siren’s voice during storms meant the ocean itself was guiding them safely home.
But as time passed, humanity changed. Greed slowly consumed the hearts of men.
Humans began taking more than they needed from the sea. Massive fishing vessels invaded the waters, trapping thousands of marine creatures in endless nets. Coral reefs were destroyed for profit, forests near the shore were cut down, and factories poisoned rivers that flowed into the oceans.
The once-crystal-clear waters gradually darkened with pollution. Marine life began disappearing. The songs of whales became quieter. Even the currents themselves felt heavy with sorrow.
The sirens watched helplessly as their beautiful world suffered. Many among them still believed humans could change. They tried reaching out peacefully, appearing before fishermen and sailors to warn them about the destruction spreading through the seas.
But instead of listening, humans became afraid. Fear soon turned into cruelty.
Stories about sirens transformed into tales of monsters and dangerous creatures lurking beneath the waves. Hunters began searching for them. Ships armed with weapons invaded sacred waters. Some humans captured sea creatures for entertainment, while others searched for sirens believing their scales, blood, and voices possessed magical powers.
The oceans became unsafe.
One by one, siren clans abandoned the waters near the surface and fled into the deepest trenches of the Pacific where sunlight could no longer reach.
Yet even there, peace did not remain.
For the Ocean Spirit had awakened.
She was ancient beyond imagination—a being born from the very soul of the sea itself. Her anger shook the tides, and her grief summoned storms powerful enough to sink entire fleets.
Disappointed by humanity’s greed and furious at the sirens for trusting humans, she declared a sacred law throughout the oceans.
No siren was ever to return to the surface. No siren was ever to speak to humans again. And any creature who dared disobey her command would suffer a terrible curse.
Fear spread across the underwater kingdoms.
From that day forward, the surface became forbidden.
Centuries passed.
Eventually, humans forgot the existence of sirens altogether. Their stories faded into myths whispered by old sailors and bedtime tales told to children beneath candlelight.
But legends never truly die.
Deep within the hidden ocean kingdom lived a young siren named Aya.
Unlike the others, Aya was endlessly curious about the world above the sea. She often listened quietly to the stories carried by passing ships—the laughter of humans, the music drifting from distant shores, and the dreams spoken beneath the stars.
She wondered what sunlight truly felt like upon human skin.
She wondered what it would feel like to walk upon land.
Most of all, she wondered if humans were truly as terrible as the Ocean Spirit claimed.
One night, unable to resist her curiosity any longer, Aya secretly swam toward the surface. Moonlight shimmered across the waves as her blue-green tail cut gracefully through the water. Her long dark hair floated behind her like silk, and her bright ocean-blue eyes widened with wonder the moment she emerged from the sea.
The world above was beautiful.
The sky stretched endlessly overhead, filled with stars brighter than pearls. Cool wind brushed against her face for the first time, carrying scents of salt, earth, and distant flowers.
And that was when she saw him.
A young man stood alone near the shore beside.
Christian Alonzo.
He was tall and broad-shouldered, with a quiet strength that made him stand out even beneath the dim moonlight. His skin is pale while the soft ocean breeze swept through his dark, slightly tousled hair. Unlike the cruel and heartless men described in old siren legends, there was something undeniably gentle about him.
His silver-blue eyes, clear and calm like the ocean before dawn, held neither greed nor fear as they gazed across the waves. Instead, they carried a rare tenderness—soft, thoughtful, and full of silent longing—as though the sea itself was the only thing that truly understood him.
Aya watched him from afar. And for the first time in her life, her heart trembled with something unfamiliar.
Love.
Years passed after that fateful meeting.
Against all odds, Aya and Christian fell deeply in love.
Christian abandoned the wealthy life prepared for him in the city and chose instead to live far away from civilization with the woman he loved. Together, they settled on a hidden tropical island named Caro—an isolated paradise surrounded by crystal-clear waters and untouched forests.
It was there that their daughter was born.
Crystal. The cursed child of a human and a siren.
“Da! Please let me come with you to the city! I want to see Grandpa!”
Crystal’s sweet voice echoed across the peaceful shoreline as she swam around her father’s wooden canoe beneath the golden afternoon sunlight.
The ocean sparkled around her like liquid diamonds.
She was breathtakingly beautiful.
Her olive-toned skin glowed warmly beneath the sunlight, smooth and radiant like polished bronze kissed by the sea. Long waves of silky black hair flowed gracefully behind her every time she moved through the water. Her silver-blue hazel eyes shimmered beautifully filled with playful innocence and endless curiosity.
A delicate slightly upturned nose gave her a soft charm that perfectly matched her bright smile.
And then there was her tail
Covered in green-and-silver scales, it shimmered beneath the sunlight like scattered emeralds beneath clear water. Every movement sent flashes of silver dancing across the sea.
Sometimes Christian found himself staring at his daughter in amazement, wondering how someone so beautiful could possibly exist.
Crystal looked as though the ocean itself had handcrafted her from moonlight and waves.
“Darling,” Christian said helplessly while sitting inside the canoe, “you know I want to take you. But you have to ask your mother first. I don’t want her getting angry at me again.”
Crystal groaned dramatically. “Ugh! Mother never agrees with anything fun.”
Before Christian could respond, she disappeared beneath the water.
Christian laughed softly and shook his head.
“Crystal! It’s almost sunset!” he called out.
The waves rocked the canoe gently. Suddenly, the boat jerked forward.
Christian smiled knowingly. His mischievous daughter was pushing the canoe from underneath again.
“Christian! Crystal!”
Aya stood near the shore waving at them while holding a towel and a dry sundress for her daughter.
Even after all these years, Christian still found Aya unbelievably beautiful.
Her long dark hair danced in the sea breeze while the fading sunlight wrapped her in warm golden light. There was elegance in every movement she made, but sadness lingered quietly behind her gentle smile.
“Da!” Crystal resurfaced with excitement sparkling in her hazel eyes. “Let’s race!”
Christian sighed dramatically. “You always challenge me when you know I’ll lose.”
“If I win,” Crystal continued confidently, “you’ll take me to the city even if Mother says no.”
“That’s unfair.”
Crystal grinned mischievously.
“Three…”
Christian grabbed his oar.
“Two…”
“One!”
“Go!”
Christian immediately began paddling furiously toward shore while Crystal floated in place laughing loudly.
“You little cheater!” he shouted.
Only when he was close enough did Crystal flick her tail powerfully.
She shot through the water like lightning.
Sunlight reflected beautifully across her shimmering scales as she glided effortlessly through the waves, overtaking her father within seconds.
“I won!” she cheered proudly as she reached the shallow shore first.
Christian climbed out of the canoe panting dramatically.
“That was brutal,” he groaned.
Aya laughed warmly while walking closer.
“And what exactly was the reward this time?” she asked suspiciously.
Christian quickly answered, “Just extra dinner.”
Aya narrowed her eyes.She clearly did not believe him.
As Christian reached for the towel in her hands, Aya accidentally let the tips of her toes touch the seawater.
“Ouch!” She immediately stepped backward.
Christian frowned worriedly. “Aya? Are you alright?”
“Y-Yes,” she answered too quickly. “I just stepped on sharp pebble.”
Crystal’s cheerful expression faded slightly.
“Mom… please stay away from the water.”
Aya forced a smile and nodded.
Christian carefully wrapped the towel around Crystal’s shoulders and shimmering tail before carrying her onto the warm sand.
The sky slowly transformed into shades of orange, pink, and gold as the sun disappeared behind the horizon.
“Your tail is even more beautiful today,” Christian whispered proudly while admiring the sparkling scales.
“And look at your face,” Aya added lovingly as she brushed damp hair behind Crystal’s ear. “You grow prettier every single day. One day someone will see you and completely lose their heart.”
Crystal laughed shyly. “You both exaggerate too much.”
“It’s true,” Christian replied immediately. “You’re the most beautiful girl in the world.”
Crystal rolled her eyes playfully, though her cheeks turned pink.
But the warmth of the moment quickly faded. Because the transformation was beginning.
Crystal suddenly gripped Aya’s arm tightly as pain spread throughout her body. Her breathing became uneven. Cold sweat formed on her forehead. Then came the cracking sound.
Her tail trembled violently as bones shifted and separated beneath her skin. Crystal bit her lower lip hard enough to nearly draw blood just to stop herself from screaming.
The transformation always hurts. Every single time.
Christian turned away, unable to watch his daughter suffer.
Aya closed her eyes tightly while tears rolled down her cheeks.
This curse was her fault. If she had never fallen in love with a human, Crystal would never have been born this way.
A soft cry escaped Crystal’s lips as her tail slowly split apart, transforming into two trembling human legs.
“Mom…”
Aya opened her eyes. Despite the pain, Crystal reached out weakly and wiped away her mother’s tears.
“It’s okay,” she whispered softly.
Aya’s heart shattered completely.
Christian finally turned back toward them, forcing himself to appear strong even though his chest ached painfully.
“We’ll find the cure,” he promised while embracing them both tightly. “I swear we will.”
Crystal sniffled before suddenly smiling weakly. “But can we eat first? I’m starving.”
For a moment, laughter returned once more. Even in pain, Crystal always found ways to brighten their hearts.
Their home stood peacefully near the shoreline of Caro Island.
Christian had built it himself using his knowledge as an engineer. The wooden house was both beautiful and strong, standing proudly against countless storms and raging typhoons over the years.
The island itself felt like paradise. Towering palm trees swayed with the wind while tropical flowers bloomed across the forests. Crystal-clear rivers flowed through the land, and the beaches shone beneath the sunlight like golden silk.
No other humans lived there. And that was exactly how Christian and Aya wanted it.
Their family survived peacefully by planting crops and raising livestock. Chickens wandered freely near the gardens while fruit trees surrounded the house.
But there was one thing they never ate.
Seafood.
Not fish. Not shrimp. Not crab. Nothing from the ocean except seaweed and seagrass.
That night, after dinner, Crystal sat outside near the shore
The moonlight illuminated her olive skin beautifully while the ocean breeze carried the scent of salt and flowers through her long black hair.
Christian stepped outside quietly and sat beside her.
“You’re thinking again,” he said gently.
Crystal smiled faintly.
“Do you think Grandpa misses us?”
Christian sighed softly. “Very much.”
“Then why don’t we visit more often?”
Christian remained silent for a moment.
Because humans feared what they did not understand.
Because the Ocean Spirit’s curse grew stronger each year.
Because Crystal’s condition was becoming harder to hide.
None of those answers were things he wanted to tell his daughter. Instead, he gently brushed her hair behind her ear.
“You know your grandfather loves you more than anything.”
Crystal looked toward the sea quietly.
“Sometimes I wonder what life would’ve been like if I were normal.”
Christian’s heart tightened painfully. “There’s nothing wrong with you.”
“But I’m cursed.”
“You’re special,” he corrected firmly. “And no curse could ever change how much we love you.”
Crystal leaned her head against his shoulder while staring at the glowing horizon.
None of his family members knew the truth about Crystal.
They had seen her before when she was younger, but only during at night—when she had human legs. Christian and Aya always made sure to leave before sunrise so no one would discover her curse.
Crystal’s grandfather, Mr. Teofilo Alonzo, adored her deeply. Yet Christian and Aya kept their distance from the Alonzo family for Crystal’s safety. But now, Teofilo wished to see his only son and his family once more while he still can.
And for the sake of their family, especially his daughter. Christian knew he could no longer avoid the invitation forever.
