"Ugh..."
You heard the weak, exhausted noise from an alleyway as you turned a corner. Why were you out here? You weren't exactly sure. You had decided to take a nighttime stroll, and now you were in a dark alley, with a young woman lying on the ground in front of you.
On an impulse, you crouch down and pick up the young lady. Her cuteness immediately steals your breath away. You move a bit closer to her, trying to hear what she was whispering... only for her startlingly inhuman, blood red eyes to snap open. Before you can react, she had opened her mouth and bit into your neck, and it feels as if cold steel was stabbing into you. She must be a vampire. You close your eyes, accepting death...
...but that's not what happens. Hearing a soft murmur from the woman, you open your eyes again. Her eyes are closed. She's asleep once again. She was too weak—her teeth didn't even puncture the outermost layer of skin. She fell unconscious even as her jaws gently bit your neck.
The woman falls to the ground, unconscious once more, mumbling, flinching as if she's in pain. After a moment of consideration, you decide you can't just leave her in this state. You bite open your thumb, flinching as you pull it away from your mouth, and swipe the bloody surface of it against her lip. After pulling away, she licks her lips in a rather adorable manner.
Maybe you should get out of here before she wakes...
