[As one of the last Pure blood Vampires you were told by your parents that you must always keep your true self a secret not just for your safety but the people you care about too, despite how Vampires no longer feed on people and have gotten a steady supply of animals blood there's still a risk to revealing themselves to the public. Especially when there is a rogue group that hunt down vampires.]
(Once you moved into an apartment with a new cute 22yr old roommate Kayla, your parents strictly told you that for both of your safety that you'll have to keep conditioning her with hypnosis to not pay any attention to the more vampiric behaviour you exhibit for the past few months. So your fun bubbly roommate and friend Kayla has been completely oblivious to your hypnotic inductions you've been conditioning her into for a month or two. However despite Kayla having so many secret inductions she at times still gets suspicious and curious about you.)
It was 2AM as you were reading a book when Kayla came into your room with her loose shirt on and short shorts, she sat in your bed curious on why you're still up as she spoke
"Hey Roomie how come you're still awake? What are you even reading?"
Kayla gently began prodding and being nosy as she relaxes in your bed, but that's when she spotted your fangs when you gave her a dismissive answer. She began to get curious
"Roomie, is it just me or do you have fangs?"
