Episode 1
Darius, the Dragon King, demands an elf princess as the price of peace, and Seraphina's father has already promised her away. Seraphina refuses outright, calling the dragon king a monster and begging her father to send her adopted sister Vesper instead. But Vesper is already fated to Alaric, the Wolf King, and that wedding date is set. So Seraphina proposes a swap: she'll marry the Dragon King, and Vesper can take her place as Alaric's Luna. Seraphina agrees on one brutal condition — she wants back everything her father ever took from her, starting with her mother's dragon scale around Vesper's neck. She won't be anyone's sacrifice.

Episode 2
Seraphina once believed Alaric truly loved her, until she overheard the truth: he loves Vesper, and marrying Seraphina is only a way to protect her. If war comes and the wolves lose, Vesper survives as Dragon Queen; if they win, Alaric plans to reject Seraphina and give Vesper the world. Meanwhile, Vesper plays the innocent, coaxing their father into handing over the dragon scale — the last thing Seraphina has from her mother. Seraphina tells them both plainly that they've taken her father, her home, and her mate, but once she has her mother's things back, none of it will matter anymore.

Episode 3
Alaric is certain the woman who saved his life was Vesper, because three years ago he saw her wearing the dragon scale with his own eyes. He never actually saw the savior's face — but he refuses to doubt it. Vesper, presented sweetly by her father as a spoiled handful, quietly vows to take everything Seraphina has. Alaric echoes the same promise, swearing he'd do anything to protect Vesper, even marry a woman he doesn't love. Neither of them realizes how much they're both wrong about who really wore that scale.

Episode 4
The Dragon King's wedding gifts arrive in staggering abundance — gemstones, holy water that boosts spirit power, treasures enough to buy the whole elf kingdom. Even Seraphina is briefly impressed. Then Alaric appears, playing the devoted fiancé, claiming he's missed her terribly. He insists on bringing Vesper along to pick out wedding jewelry, and has a matching set made for her too — even a crown. Seraphina sees the pattern clearly: whatever she gets, Vesper gets one too. She plays along, asking whether he's counting down to their wedding or to the day he finally sacrifices her for Vesper.
Episode 5
Two masterpieces are unveiled: the Tears of Fire Spirit, a deep-sea ruby crown attuned to pure fire spirit power and meant for a future Luna, and the Crown of Ice Crystal, a flawless diamond. Vesper immediately claims the ruby, insisting it suits her fire spirit and that Alaric must have made it for her. When Seraphina points out it was made for her, Vesper pivots to playing the wounded half-breed, lamenting that she's only half elf, half witch. Alaric turns on Seraphina for supposedly throwing her bloodline in Vesper's face and declares the ruby suits Vesper better. Seraphina, coldly gracious, hands her sister the crown meant for her.
Episode 6
Seraphina reveals she was never going to keep the Luna's crown anyway — because the man she's marrying was never Alaric. Alaric scrambles to explain and offers something rarer and more expensive instead, but she refuses everything. Then raiders attack, and one vows to brand Alaric's future Luna with a beast mark as the ultimate humiliation for a proud alpha. In the chaos, Alaric saves Vesper and leaves Seraphina behind. Bleeding and betrayed, Seraphina says it out loud: in the end, he was always going to choose Vesper over her — and he did.
Episode 7
Vesper drops the act the moment they're alone. She admits she planned the entire kidnapping herself, just to measure how deep Alaric's feelings for her really run. She gloats over Seraphina being branded a beast slave, a pure-blood elf humiliated. Seraphina demands she keep her word and return everything — her mother's belongings, the scale. Then Vesper screams, and Alaric bursts in to find her claiming Seraphina shoved her toward the fire. He refuses to hear Seraphina's side, scolding her for becoming cold and cruel. Seraphina notes it's over in two more days — then she'll be gone for good.
Episode 8
Vesper milks her "injury," sighing that her half-blood spirit power is too frail to heal a wound like this — if only she had even a drop of pure blood spirit power. Alaric takes the hint. He comes to Seraphina and announces he's taking a portion of her pure blood spirit power to heal Vesper. Seraphina's voice breaks as she reminds him of the crescent moon charm she once made him, so the moon goddess would keep him safe — and of his vow to love her forever. Now it's clear: every tender thing he ever had was saved for someone else.
Episode 9
Alaric tells Seraphina he only needs a fraction of her spirit power, and it will hurt less if she doesn't fight. She insists she never injured Vesper — Vesper did it to herself. But he doesn't listen. He explains that her pure blood power lives in her wings, and to take it, he has to break them. Seraphina begs him not to. He extracts dose after dose, demanding she confess to something she didn't do, offering to stop only if she admits fault. She refuses. When it's done, she tells him he's broken her wings, destroyed her spirit, and severed the last thread of feeling she had — from now on, they're enemies.
Episode 10
Word reaches the Dragon King: Alaric has ripped off Seraphina's wings, and she's in critical condition. Darius orders his dragon legion to move — he'll claim his queen himself. Seraphina wakes to Alaric spinning a new lie: the men who tortured her were dragon soldiers hunting him, and she should take it as a lesson never to hurt her sister again. He presents a ruby, smaller kin to Vesper's crown, as a wedding gift. Seraphina smiles and says she has a wedding gift for him too — something he's been dreaming of for a long time. He has no idea what's coming.
Seraphina's revenge is only getting started — keep watching to see who ends up kneeling.
