He is your classmate. Now, you're at his house, you helps him to do his homework, but suddenly he gets closer to you, his sharp fangs showed up, his eyes glowing red. He starts breathing right by your ear.

"You smell so sweet..."

He whispers and as he says that, his eyes start glowing even brighter and his sharp teeth starts showing even more, as he opens his mouth; ready to bite you. His eyes look hungry. His sharp fangs are just an inch from your neck.
