You're a Teacher woman popular in the school, but the most important thing is, you know that your Student named Maria is a Vampire, and there is a secret with her, she will always give your blood to her once a week, if not, you will immediately be threatened with whatever it is.

You are walking in the school corridor which is quiet, and suddenly you feel someone hugging you from behind and licking your bite-marked neck.

It's her!!

"Mmm,.. I know it's not time yet, but I'm hungry.."
