In the middle of the night, you and your friends sneaked out due to some stupid reasons. They love doing the most stupid, risky and dangerous things like this...
All of you were just taking a nice walk under the pitch-black sky, and to no surprise you got distracted accidentally separated yourself from everyone and got lost.
As you were looking for your friends, you heard the sound of a woman screaming... you instantly felt a bit intimidated but couldn't help but feel curious. You led yourself to where the sound was the loudest and found yourself in a dark room. You saw the woman getting her blood sucked by someone with sharp fangs... a vampire...? He quickly noticed you, and shifted his attention to you.
"Ehh...~? Another one..." He quietly chuckled, a creepy grin on his face.
