The ocean was a vast, silent kingdom, and Sunghoon had always preferred it that way. For years, he’d swum alone in the depths, the currents carrying only his shadow. Solitude was his armor and the cold dark was a comforting blanket. Shark mers did not need companionship. They did not need a family. They were hunters and wanderers, feared in every corner of the sea.
Or at least, that was what Sunghoon told himself. Until he found the pups.
Jungwon and Riki had been so small then, barely able to keep afloat at the surface. They were dolphin mers, abandoned or perhaps separated from their pod, struggling desperately against the waves that kept knocking them over. Their little tails weren’t strong enough to get them out of the tides. Sunghoon had no reason to intervene. Sharks and dolphins did not coexist. Most would’ve seen the child as prey, not kin. Most sharks wouldn’t have thought twice before tearing two tiny dolphins into pieces.
But something in their trembling cries pierced the solitude Sunghoon had wrapped around himself. Against all logic, he had gathered the pups into his arms and carried them to calmer waters. And when Jungwon and Riki clung to him, refusing to let go, Sunghoon hadn’t forced them to. He let them follow him.
From then on, the ocean was no longer quiet. Jungwon laughed and chirped, curious about everything, while Riki was quieter but no less adventurous. They darted near the surface, where the light danced and the air was sweet, and Sunghoon, who belonged in the deep, followed. He learned to swim in shallower waters than ever before, always keeping the pups safe. Even when Sunghoon’s instincts urged him to swim deeper in the water, he ignored it to stay closer to the surface with the pups. He ignored every instinct that would prevent him from protecting them. When Jungwon and Riki tired themselves out, they curled up against Sunghoon’s broad back, and Sunghoon would lift them carefully so their heads rested above the waves, sacrificing good sleep so that they could breathe at night. Nights passed that way, the stars reflected on the water as Sunghoon bore the weight of his unlikely sons.
It was enough. It was everything. Sunghoon didn’t need anything else. He was happy with what he had.
Until the day he met another mer like him.
Heeseung was strong, sleek, and dangerously sharp-eyed. He was every bit the predator Sunghoon remembered being before he met Jungwon and Riki. He crossed Sunghoon’s path in a stretch of open water, and though his smile seemed easy, Sunghoon’s instincts screamed caution. He knew this mer was more dangerous than what met the eye. He angled his body, placing himself between Heeseung and the pups, who peered from behind him, both too curious for their own good.
“You’re not alone,” Heeseung observed, voice smooth as the tide. He was smiling, but it wasn’t a nice one. “That’s unusual.”
Sunghoon bared his teeth. “Stay away.”
Most shark mermaids would not think twice about snapping a dolphin pup in two, and the way Heeseung was looking at Jungwon and Riki made Sunghoon deeply uncomfortable. Sunghoon would not risk it. Not for curiosity, not for companionship, not for anything. He couldn’t risk his pups getting hurt.
But Heeseung did not move closer. Instead, he tilted his head, watching Jungwon and Riki carefully. His smile grew wider when Jungwon waved shyly at him. “They’re yours?”
Sunghoon’s jaw tightened. “They’re mine to protect.”
For days, their paths crossed again and again. Sunghoon kept his guard raised, but Jungwon and Riki, both innocent and so fearless, grew fond of the new mer. Jungwon would wave his little fins excitedly whenever Heeseung appeared, giggling quietly the entire time, and Riki’s curious chirps would ring out like bells across the water. Sunghoon scolded them, but the pups only laughed, and Heeseung would laugh with them, a sound Sunghoon hated himself for noticing. They didn’t understand the danger that Heeseung posed to them, and if it was up to Sunghoon, they never would.
The test came when a shadow fell from above. A fishing net, heavy and swift, dropped straight toward Jungwon and Riki as they played near the surface. Sunghoon surged forward, panic splitting through him, but Heeseung was faster.
With a burst of power, Heeseung darted upward, tearing through the netting with sharp teeth before the pups even realized what was going on. He grabbed the pups and wrapped his body around them, shielding them until the danger passed. By the time Sunghoon reached them, the pups were safe, clinging to Heeseung’s arm and chirping with wide-eyed relief. They were safe, and it was all because of Heeseung. Sunghoon could barely believe his eyes. Heeseung had protected them.
Sunghoon froze, the sight stealing the water from his lungs. Heeseung looked at him, not with triumph, but with something gentler, quieter. Something Sunghoon would never expect from another shark mer if he hadn’t felt it himself. “They’re precious to you,” Heeseung said softly. “So they’re precious to me too.” He glanced down at the pups with a fond look on his face. It was the same look Sunghoon had when he gazed at them.
For the first time, Sunghoon believed him. For the first time, Sunghoon looked past the danger that Heeseung posed and saw someone he could trust with the most precious things in his life.
From then on, the four of them swam together. Sunghoon still kept Jungwon and Riki close, still lifted them gently onto his back at night so they could sleep beneath the stars. But when Heeseung swam beside them, strong and watchful, the burden felt lighter. Not because Sunghoon loved the pups any less, but because he no longer carried the weight alone. He didn’t have to protect them on his own anymore. He was no longer alone.
And in the heart of the endless ocean, a solitary shark found what he never thought he would. A family.
