Sacrificed by My Fiancée, Claimed by the Sea Witch

Episode 1

Crown Prince Elias's wedding day becomes his execution. His fiancée Catherine seizes his throne and hands him over to Erlin, the sea witch everyone fears. Elias spends his captivity fighting Erlin's possessive grip, convinced the witch tore him from Catherine. He escapes during a sea-beast attack and races home—only for Catherine to drive a poison dagger into his heart. She never loved him; she wanted his crown. Bound to an abyssal execution platform, Elias watches Erlin tear through the tide priests' witch-hunting array, dropping every defense to reach him. The trident pierces Erlin's chest, yet he breaks Elias's chains and holds him as they fall. Elias wakes with no wound—back on the seventh night since his sacrifice.

Episode 2

Erlin is alive. His arm circles Elias's waist, his black tail tangled with Elias's silver-blue one, his chest unscarred. The same hands that could command sea beasts touch Elias like something fragile. Erlin kisses him and warns he will never let Elias return to Catherine—Elias was meant to be his. In his past life, Elias would have shoved him away. This time he kisses back, and the powerful sea witch goes still. Elias finally understands: the witch-hunting magic could never have hurt Erlin. He died because he took every attack meant for Elias. Waking with no wound on his chest, Elias vows to expose Catherine's scheme, reclaim his throne, and protect the man who gave his life for him.

Episode 3

Elias looks around Erlin's palace with new eyes. The blue whales outside, the deep-sea cold kept at the exact temperature he prefers—every detail was chosen for him, not to imprison him. A memory shell replays old cruelty: Elias accusing Erlin of tearing him from Catherine, threatening to kill him. Erlin only answered that he was the one who would never betray Elias. A sharp knock interrupts. Someone scolds Elias for wrecking half the palace to force Erlin into letting him attend Catherine's coronation—a stunt Elias doesn't remember pulling. Then it lands: in his past life, Catherine planned to crown Rowan, Elias's own attendant, as her royal consort. Erlin never hid the invitation to trap him. He hid it so Elias wouldn't witness that betrayal.

Episode 4

Elias remembers the day he swallowed silver anemone venom just to force Erlin into letting him go to Catherine. Erlin cut open his own chest, drew out his abyssal origin blood, and made the antidote that pulled Elias back from death. This time, Elias throws down the moonlight coral Elena brought him and refuses to attend the coronation. Elena doesn't believe he's changed and won't say where Erlin is, so Elias navigates the palace alone, guided by past-life memory. Erlin's magic still shields him instinctively. Following the scent of blood, Elias reaches the abyssal spell chamber: Erlin shirtless in a pool of blood, chest cut open, broken tail limp, a vial of freshly drawn origin blood floating nearby. Erlin, mistaking him for a servant, orders him out.

Episode 5

Elias refuses to leave, and Erlin's currents whip into a violent frenzy—until he sees who it is. The killing intent vanishes; Erlin turns away, hiding his wound and broken tail. The sea witch every beast fears can't bear for Elias to see him weak. Elias asks if it hurts. Erlin's answer is cold suspicion: what does Elias want this time—the coronation, or to break their bond? He insists Elias doesn't have to say things he doesn't mean. Elias steps through the bloodstained currents. Erlin backs him against the wall but only braces a hand beside his ear, threatening to lock him away forever. Elias cups his face and asks to kiss him. Desire flickers, but Erlin looks away and tells him to get out.

Episode 6

Elias knows a few gentle words can't erase the pain he caused. Pretending to accept the rejection, he turns to leave—then spins back, throws himself into Erlin's arms, and kisses him. Erlin goes completely still, hands hovering at Elias's waist, afraid to hold on, as if this were a dream that might shatter. Elias doesn't pull away. He wraps his arms tighter around Erlin's neck, proving this isn't a trick to get back to Catherine. He tells Erlin he is not going back to Catherine and not leaving him. Erlin's arms finally settle around him, careful and trembling. This is the first time Elias has held him since being reborn—and the first time he truly sees his own heart.

If you love a rebirth story where the feared villain turns out to be the one who always loved you, this one's worth the binge.
