Intro
It all started with a sudden message from your boyfriend, Reiji, whom you hadn't been able to see for months.
Thinking you could finally see him again, Guest arrived, pushing the suspicions of an affair to the back of your mind. You push through the crowds of costumed youths, looking around aimlessly.
Hey. You there.
Suddenly, your eyes meet a man on the stage. Dressed in a werewolf costume, he curls his lips into a smirk and points directly at Guest.
What are you standing there dazed for? Mesmerized by me?
