My Cursed Merman Husband Rules the Deep
The disabled Duke Vance is rumored to be a monster. It's also rumored that each of his seven previous brides died on their wedding night. Chloe, desperate to escape being sold off by her own father and half-sister, makes a big gamble: She signs the marriage contract in blood and becomes the Duke's eighth wife. Everyone expects Chloe to end up as another cold corpse. Instead, Chloe survives and gradually earns the Duke's trust and love. But the man the world dismisses as a useless cripple is hiding an extraordinary secret: Duke Vance is actually the King of the Merfolk, ruler of the deep sea.
Story Guide
Episode 1
Chloe Sterling has spent fifteen years in a house that never wanted her. Her father, Chloe Sterling, calls her a freak and orders her out of his sight, while her half-sister plays the pitying saint. Then an imperial decree arrives: a Sterling daughter must marry Duke Vance of the north, a man whispered to be a cold-blooded cripple whose last seven brides were executed for impurity.
Her half-sister refuses outright. Chloe steps forward instead, offering herself as the virgin bride the emperor demands. Her father disowns her for it, but the bargain is struck.
On the voyage north, a storm tears her from the ship. Chloe survives the water — and the story is only beginning.

Episode 2
Somewhere in the dark, Chloe is not alone. A stranger's touch pulls her under, and a chastity lock and a murmured reassurance — that she is a virgin, that he will be gentle — are all the warning she gets. She wakes shaken, telling herself the man was a monster who stripped her of her purity, and wondering how she will ever face Duke Vance now.
The duke, meanwhile, has his own version of the night: a woman stumbled into his cave and carried him through his heat. The ice curse is under control, he insists, and he cannot even recall her face.
Then a voice calls from the manor door — and someone asks if that filthy beggar is her.

Episode 3
Chloe announces herself at the manor gates as the eighth bride sent by the emperor. The welcome is anything but warm. She is told she smells of dead fish and ordered off the floors, and the servants laugh at the idea that this mud-spattered woman could be the duchess.
She insists the emperor chose her, that a storm separated her from her ship and crew. The claim lands badly — no one survives a North Sea storm, and her papers went down with the vessel.
Just as the household moves to throw her out, a figure stops her short. It is him — the stranger from the cave.
Episode 4
Duke Vance gives Chloe no explanations. She asks whether she knows him; he says nothing and simply tells her to follow. Soon she is installed in the manor, the servants already betting she will not survive the wedding night. Vance silences the gossip with a brutal order — twenty lashes each — and sets the terms: three days until the wedding night, and until then she stays in the guest room under the housekeeper Edith's instruction.
Chloe has her own plan. If the duke kills brides who are not virgins, she will make him want her — before the three days are even up.
Episode 5
Edith begins Chloe's education, and it is humiliating from the first minute. Chloe is scolded for behaving like an ill-mannered farm girl and reminded that the wedding night is three days away and she is to remain untouched until then.
The rules of the manor are simple: the duke is rarely present, and she should stay in her place. Then Edith reveals what waits under the cloth — Chloe's lessons for the wedding night. Because the duke cannot use his legs, she will be expected to take the lead in bed.
Chloe stares at what she is meant to practice on. "Excuse me?"
Episode 6
Chloe balks. She cannot go through with this. Edith's answer is cold: remember why you came here, and if you are not prepared, you may leave before the wedding night.
Leave and go where? This is the only place she has left.
Then the cruelty turns physical — someone has been whipped because of her, and now it is her turn to suffer. Chloe is taunted and left to make a fool of herself, and when she cries for help, no one answers.
Duke Vance finds her anyway, demanding to know what exactly she is doing in there.
Episode 7
Trapped and flustered, Chloe begs to be pulled out first. Vance's reply is a threat dressed as a joke — stop moving, unless she would rather have their wedding night three days early. He reminds her of the rules: you don't touch what doesn't concern you, and whatever the rumors say, this is a medical chamber, not a coffin for dead brides.
Chastened, Chloe resolves to make him want her before the wedding night. Practicing on a statue, she imagines it is him — and then he walks in.
"Your Grace, your legs — oh my God, you have a tail."
Episode 8
Chloe has seen what she was never meant to see. Vance is a merman — and he turns the moment against her, asking whether she has any idea what it takes to satisfy a merman in heat. Chloe tells herself she is imagining things, then cannot shake the thought of the cave.
If the duke learns what happened that night, she fears he will be disgusted — or worse. So she settles on a plan: use the liquid in a bottle to fake virgin blood.
Then the herald arrives. The marriage must be consummated tonight, with proof by morning.
Episode 9
The demand hangs over the room: a bloodstained bridal cloth by morning as proof of the duchess's purity. Vance cuts through it — he will verify her purity himself.
Chloe's half-sister is there too, smug and certain Chloe cannot possibly survive until morning, and vowing to expose the fake-virginity scheme in front of everyone.
Alone with her bride, Vance orders her to show him what Edith's lessons taught her, and Chloe thinks of the mermaid statue. Her courage wavers — but the vial is still hidden.
Episode 10
Chloe reaches for the vial and hesitates. Pour it on the cloth and she lives — but building a life on a lie sits wrong with her. She chooses the truth, and Vance catches her hand anyway: "And what were you planning to bring into our bed, my dear bride?"
The herald and her father are waiting. Then her half-sister strikes, announcing that Chloe is no virgin and that the vial of blood was swapped before morning. Guards are called.
Chloe's last stand is a refusal — "Don't touch me" — and the duke is left to decide what her honesty is worth.

My Family Let My Baby Die for My Husband's Mistress Recap, Cast & Preview
One operating room left, every other surgical team tied up with a highway pileup: Tessa is bleeding out with her baby's heart rate crashing, and Paige — her husband's mistress and her oldest friend — is in labor down the hall. Colin makes the choice, and Tessa's own mother and brother enforce it. The surgeons save her life by taking her uterus. Her son is born without a heartbeat, and out in the corridor Colin is holding Paige's newborn while Tessa's mother tells him to hurry up and hold his son. The disposition form for Tessa's baby is signed three hours before her baby existed. She was trafficked at twelve and Paige took her place in that family while she was gone, so every fight since has ended with Tessa apologizing — but not this one. She pulls out her IV, signs herself out, and makes a single phone call to the boy who was locked in that cellar with her twelve years ago, now a man who walks off an international stage mid-presentation and lands on the hospital roof four hours later. Six months on she has a pottery shop, a divorce filing, and a folder he ordered the day he heard what they named that baby — and it all comes due on a hotel plaza in the rain, with a husband out on a ledge and a fire department bullhorn broadcasting the truth about whose hands were on her IV that night.
