Mommy by Mistake for the Abyssal Tyrant’s Baby

Episode 1

Elena's submarine explodes, dragging her into the forbidden trench beneath the Seacourt. She should be drowning—instead, she's breathing underwater. Then a terrifying figure glides out of the darkness: black scales, golden eyes, claws reaching for her throat. He tells her her blood will wake the power sleeping inside him.

Her only gamble is a lie. She screams that she's his fiancée. Silence. Then a small boy swims out—Lucian, a mini replica of the lethal prince, holding a glowing blue pearl. He grabs her wrist, and a silver-blue crescent mark rises on her skin. "She is not your fiancée," he says. Elena braces for death. Instead: "I think she's my mommy."

Episode 2

Before Elena can process Lucian's words, Kael's massive tail whips around her waist and yanks her into the freezing abyss. Lucian swims effortlessly beside them while shapes with jagged teeth and glowing eyes watch from the coral walls—then recoil the moment Kael passes.

When his tail loosens, she panics and grabs his bare waist. Surprisingly, he doesn't shake her off. He drags them into a forgotten abandoned palace. She kicks a golden trunk and loses her balance in the dark. "Did I seriously father an heir with a night-blind woman?" he mocks. She fires back that she still insisted on marrying him. A suffocating silence falls—until Lucian asks if his father really loved Mommy that much.

Episode 3

Kael doesn't fully buy her story. With no powers and no chance of surviving the monster-infested ocean floor alone, Elena has to chain herself to him and his son. "You claim to be my fiancée—where is the proof?" he demands.

She reaches for the worn silver half-moon shell pendant around her neck, improvising a story: it's his promise token, and when the two moonshells join, they form the royal crest. She presses against his chest, whispering that he once called her his greatest treasure. A faint red flush spreads across the sea prince's cheeks. He shoves her away and flees into the dark. Outside, Lucian notices his father's red ear tips. "She might actually be my mate," Kael admits.

Episode 4

Over the next few days, Kael barely shows up—only returning to toss her looted canned food and pretty dresses before vanishing into the deep. Elena feels like a stray pet. Lucian sneaks over daily, munching on spam, and her heart softens even as she plots an escape. She asks him if there's a secret pathway back to the surface.

Before he can answer, Kael staggers in and collapses, a bone-deep wound oozing black venomous blood across his chest. Dozens of crimson eyes ignite outside, scavengers smelling weakness. Lucian fetches a black healing pill, but Kael's jaw is locked. Lucian suggests passing the pill with her mouth—or a kiss. Elena forces his jaw open, and his icy golden eyes snap awake.

Episode 5

Kael snaps his jaw back into place and orders her off him. The pill works fast—his black blood stops flowing within seconds. When his tunic slips, Elena quips that they're engaged, so it's nothing she hasn't seen. "Do that again and I'll slit your throat," he warns.

Then her heart violently contracts. Bone-chilling frost erupts through her veins—she touched his siren venom while wiping his chest. Craving warmth, she lunges and throws her arms around his neck. Claws extend against her throat, but Lucian protests that Mommy just kissed him and wants to die for him. The claws slowly retract. Spotting the black mark on her finger, Kael lowers his head and sucks the venom out into his own body.

Episode 6

Elena wakes from the best sleep since arriving in the abyss—her face pressed against Kael's cold, muscular chest, arms locked around his waist. He stares back with bloodshot golden eyes; he hasn't slept at all. He flexes his numb arm, says he's going hunting, and vanishes.

So that's why he leaves every day—in this ruthless siren territory, it's kill or be killed. While he's gone, Lucian shivers from the venom's lingering cold. Elena wraps him in her coat, feeds him canned meat, and combs his hair, gathering intel. Lucian reveals that if a human swallows the siren's pearl, they can breathe underwater and swim freely forever. Her ticket to freedom. Then a familiar voice calls Lucian outside—and he eagerly darts toward the entrance, ignoring Kael's warning not to step out.

Episode 7

Elena swallows the siren royal pearl, and the suffocating pressure vanishes. She swims out with all her strength—and finds a dark siren with glowing crimson eyes and slimy tentacles, holding Lucian pinned in the air. She lunges forward, throwing her arms around the boy to shield him. A sharp rock cuts her cheek, and a single drop of her blood diffuses into the water. Dozens of crimson eyes ignite.

The dark siren swallows her blood, his eyes flaring with madness. He squeezes her ribs until the air leaves her lungs, sneering that Kael is trapped in a deadly ambush and isn't coming back—that her sovereign blood could restore his royal powers, yet the fool refused to touch a single hair on her. "Since he's dying anyway, I'll devour you and his precious son instead." A voice cuts through the dark: "Who did you say you're going to devour?"

Elena's lie is spiraling into something far bigger than survival—and the truth about who she really is to Kael is still waiting in the deep. Dive in and see how far this fake fiancée will go to protect the family she never knew she had.
