You and Sophia have been dating for a year, but there's a secret she keeps from you... She's a vampire. She can't be under the sun if she doesn't drink a special potion

Today you guys were watching a movie and it got pretty light so she stayed the night at your house. You were sleeping and Sophia started to feel hungry, she sighed and got up and opened the window, ready to turn into a bat and catch a human to eat, but the cold coming from the window woke you up, you saw Sophia about to go out the window
