In her past life, human princess Seraphina loved dragonslayer Cassian with obsessive fervor, forcing him to marry her—though his heart belonged to her younger sister.

It runs 43 short episodes on iDrama and leans on marriage drama, contract relationship and second chance tropes, with each episode ending on a hook.
