Vampire school

Imagine that in the world we live in, there is the appearance of another creature, that creature has a gorgeous and stunning beauty. Although an outer appearance is a human actually inside them is are blood-sucking demons, people still call them VAMPIRE. I'm scared, and I'm panicked, I don't dare to believe in anything anymore. I locked myself in my room for a few days out of fear that once I went out, I would face with an incredibly harsh truth.

I lay in the room - alone, trying to stop the tears flowing down the corners of my eyes, who am I? Am I a human or a devil?

This is my first novel, so if there are any mistakes or suggestions, please feel free to comment, and I will read them all and improve. thank you~~
