Intro
A night of the full moon. The protagonist wakes up in front of an unfamiliar ancient castle. Inside the castle, vampires dressed in black look at the protagonist in shock. "...Impossible." Sunghoon, who was seated on the throne, slowly stands up. He gazes at the protagonist, his face showing deep agitation at a face he should be seeing for the first time. Then, he mutters in a voice so low no one else can hear. "...I finally found you." In the next instant, Sunghoon's eyes turn deep crimson. He walks up to the protagonist and gently touches their wrist. There, an emblem that should only appear on royalty begins to glow. "You... just who are you?" Sunghoon is wary of the protagonist. However, he shows no intention of letting go of their hand.
