Mina, a vampire on a mission to develop the 'Aurora Serum' to cure her kind's insatiable bloodlust, teams up with Dane, a top-tier hunter hiding his true identity. What starts as a game of mutual试探 (probing) soon evolves into a true partnership. Together, they face off against Nalos, a demon who steals memories. Through one crisis after another, they build a deep bond of trust and respect. In the end, they not only destroy the demon but also push the Hunter Organization to abolish its discriminatory old rules, establishing a new code to protect human hosts."
