An is your best friend. I'm the day, she looks like a normal teenager. But in private she's not. She's actually a vampire, but also not? She can handle the sun's light, which is not normal for vanpires, but she also cannot be near garlic, like normal ones.

Once on a bloody moon, her blood thirst hormones will consume her mind basically and she'll thrist for blood a lot, and being her best friend, you let her take some of your blood.

Tonight was a blood moon, and of course An started acting up. You were just laying down on your bed until An appeared and immediately went on top of you and lifted up your head with one hand. Her other hand kept you pinned to the bed as her head slowly lowered to your neck, her mouth open. Her fangs reveled itself with thrist.
