Crimson Claim
Once the blood pact is sealed, she dies. He clings to a cure that turns out to be a lie, then buries his grief in a revenge that leaves him alone.
The warning is blunt: once the blood pact forms, she dies. William believed he could bear the toll, until the woman he loved died in his hands. He held on to the promise of an antidote, only to find it was a cruel fabrication. His grief erupted into merciless fury, and he destroyed everyone responsible one by one. When the revenge was finished, the silence was unbearable, because nothing could bring her back; kneeling at her grave with her ring, he swore his heart would belong to her forever.

The series opens on a grim warning: once the blood pact is sealed, she dies. William thought he was prepared to bear that consequence, until the woman he loved died in his hands. The promise of an antidote keeps him clinging to hope, but he soon discovers it was nothing but a cruel lie.
His bereavement breaks into ruthless fury. He sets out to destroy, one after another, everyone who contributed to her death. The opening episodes move from mourning to pursuit, each confrontation widening the trail of those he holds accountable; the show runs on short, roughly one-minute beats that keep the confrontation sequence tight.
When the revenge is finally complete, the silence left behind is unbearable, because nothing can bring her back. Kneeling at her grave and holding her ring, William makes a final vow that his heart belongs to her forever. The tone belongs to dark-fantasy and vampire romance: a fatal bond, false salvation, and a grief that curdles into vengeance before returning to a mournful end.

Editor's take
Our editors' notes on the opening arc — personal picks, not audience feedback.
The fatal-bond premise front-loads the rule that kills her, so every later choice reads against a deadline; the show sells the anguish of a cure that never existed rather than a supernatural spectacle.
The early arc shifts quickly from mourning to pursuit, and the revenge structure keeps each beat small and sharp; the mournful final note sets this apart from most vengeance shorts that end on triumph.
Best for viewers who like dark-fantasy vampire romance with a tragic, revenge-driven arc; if you want a hopeful or redemptive ending, this one leans mournful. Its distinguishing trait is that the revenge itself is framed as an empty victory, which gives the short run a somber, fatalist tone.
