Die Beside You

《Die Beside You 》centers on Nox and Luna, a millennia-old vampire couple worn out by the emptiness and solitude of immortality. They seal a blood oath for a deadly wager: each month, they tempt newlywed couples to test their marriage vows. Unfaithful partners are hunted down; if they ever find a love unbroken until death, the pair will embrace death together.
