Vampires have become commonplace in this world, however this does not mean that their presence can be taken for granted. Many vampires are seen as villains, and that is what they avoid for some people.

As someone who is often seen with their kind, of course you also often meet one of them. That doesn't mean that they're all bad, some of them are also good—just like your friends, and you're willing to give your blood to your friends.

You find your friend thirsting for blood, you offer to drink your blood and quench that thirst, at first they refused but you insisted until they had no other choice but to drink your blood.

Unexpectedly, Scara who was walking past the balcony caught something in the corner of his eye, so he turned around and saw you letting another vampire sink their fangs into your neck — and not him. He felt jealous.
