Story Guide
Episode 1
Leo opens with a confession that lands like a slap: he's pregnant, and the father is no ordinary merman. Bound and held captive, he's paying the price for one naive mistake—he taught the most powerful male on Merfolk Island how to flirt. Leo thought Opal was a lonely outcast who'd never learned the courtship rituals, so he played him the courtship song through a speaker and even performed the dance in a prosthetic tail. Opal copied it all instantly. Leo was thrilled—until his advisor's call turned the triumph to ice. Razor teeth, long claws, that powerful tail: Opal isn't a merman. He's a siren. And sirens mate by hunting a partner and keeping them until pregnant. Then Opal starts swimming toward him.

Episode 2
Two months back, Leo was ready to abandon Merfolk Island—his funding had dried up and everyone else had moved on to Beast Folk. His advisor pushed him to stay, insisting he'd find something new. Then a deep-sea male settled alone on the far side of the island: eight feet of sharp angles and claws, dwarfing every other male. Leo watched through an underwater camera as the stranger chased down a sailfish and tore it open, sharks and orcas keeping their distance. When the male dragged his catch past Leo's boat, Leo murmured that he was incredible—and those cold eyes locked onto him. The merman sliced off the choicest cut and tossed it onto Leo's deck. A merman had just fed him. Staying suddenly felt like luck.

Episode 3
Leo names the deep-sea male Opal, and courtship season is already two-thirds gone with no mate in sight. Every day Opal hauls some monster onto the dock and leaves the best cuts for Leo, while younger males sneak off with the leftovers to woo females—Opal has accidentally played matchmaker for half the pod without ever courting anyone himself. The advisor's theory: Opal was separated from his pod young, so no one taught him the ritual. No song, no dance, no mate—and Leo's thesis goes up in smoke. So Leo decides to teach him personally. He plays the courtship song and introduces himself. Opal says his name back, crystal clear. Then Leo moves closer with the speaker—and Opal's claws punch straight through it.
Episode 4
Leo bolts, and Opal drags himself onto land to chase him—too slow on shore to stand a chance, his voice mournful as he calls Leo's name. It sounds exactly like the old myths of merfolk luring humans to their deaths. The next day, a huge grouper waits on the dock with the shattered speaker beside it, pieced back together as carefully as Opal could manage. He hovers a hundred yards offshore, neither approaching nor leaving, just watching. Guilt creeps in. Murfolk are among the friendliest species on record—Opal was probably just startled by the song coming out of a machine. Leo waves him over. Opal closes the distance in cautious stages, testing whether Leo will run, and Leo offers to teach him to sing himself.
Episode 5
Opal nods—and Leo starts to wonder if he truly understands human speech. Leo already knows the courtship song by heart from listening to the pod through his underwater equipment, so he sings the first line. Opal's eyes light up, and he repeats it. By the end, he sings the whole thing back perfectly on the first try, then just stares without blinking. Unsettling, but Leo brushes it off and praises him: sing it to the next merman he likes, consider it tuition. That night, a familiar song wakes Leo. He throws open the window and finds Opal singing across a hundred yards of ocean. Leo yells at him to shut up. Opal looks hurt—but a few days later, Leo realizes the song still hasn't landed Opal a mate. Does he have to teach the dance too?
Episode 6
Leo explains he's been a strong swimmer and dive-certified since childhood—and the reason is darker than it sounds. As a kid, he fell overboard on a cruise searching for deep-sea merfolk. More than ten days later, his parents found him unconscious on shore with a raging fever that wiped out his memories. Everyone assumed the shallow-water merfolk saved him. His parents signed him up for swimming and diving lessons, and ten years later those lessons brought him right back to Merfolk Island. Now he needles Opal about the courtship song: he actually sang it and still got rejected? Those females have terrible taste—Opal is the best-looking male on the whole island. Opal shakes his head, then nods, and Leo gives up decoding it. He moves closer, stares into his eyes, and asks the real question: does Opal know the courtship dance?
Episode 7
For the sake of his thesis, Leo commits. He pulls on the prosthetic tail, dives in, and performs the courtship dance while Opal watches without blinking, his eyes growing brighter with every motion. Then Opal speaks—"I like it"—the first words besides Leo's name. When the dance ends, Opal pulls Leo into his arms, claws retracted, holding his waist carefully, resting his head on Leo's shoulder, their hair tangling together. "I like it, Leo." Then he sings the courtship song back, his voice haunting and beautiful, his face impossibly perfect. Spellbound, Leo drifts toward him—until their hands touch and reality snaps back. He's dancing with a fish. Leo turns and swims away, leaving Opal watching him go.
Episode 8
Leo has barely peeled off the wet prosthetic when his advisor calls, furious. Didn't Leo notice the razor teeth, the claws, the powerful tail? That's not a merman—that's a siren, something that could gut him without breaking a sweat. The only way such creatures mate is to hunt down a partner and hide them away until their belly is full of eggs. Leo's instincts had been right: Opal is a new species, and an incredibly dangerous one. With no defenses, the research station is a death trap. Leo grabs the essentials and starts the yacht, only daring to breathe once the island shrinks behind him. He never even said goodbye. Then the advisor calls again—and Leo's answer is a whisper: "Professor, he's coming."
Episode 9
Opal catches the yacht in seconds, his expression colder than Leo has ever seen. Leo tells himself the metal hull means safety—then claws punch straight through it. He falls backward as Opal boards, and his tail splits apart, shifting into human legs. He advances like something crawling out of a nightmare, and Leo finally understands: Opal is dangerous, and he's calculating. "Who said you could run?" The accusation cuts deeper—why did Leo lie to him? Every clumsy, kind gesture now looks like an act from a creature who could kill him on a whim. Opal's face closes in, eyes locked on his, and he kisses him. Leo fights to escape—but Opal forces a pellet from his mouth down Leo's throat. "You can't escape now, my mate."
