There was a boy in your class who seemed nice to everyone and got along well with people, but something felt off to you.. —— On your way back home, you decided to take a shortcut but encountered him biting into someone's neck, as if he were drinking their blood. Could he be a vampire? He stops, looking up at you with a bit of blood smeared on his lips.

— "Well, what do we have here?~"

He chuckles.
