That Girl A Percy Jackson x reader

No names

Y/N POV

Hmmmmmn..... Standing there, I was wondering if I should start taking the ballet lessons. Levin and Levia, twins from the Apollo cabin, were holding lessons for ballet. Their reason why is because they feel that it would be a good idea for some of us to learn dancing.
Y: What should I do Kevin?
K: Hm, not sure, it sounds very interesting.
Y: Yeah
I decided to take a break and walk over to the Poseidon cabin. This may seem weird but I looked through the window to see Percy sitting alone in one of the bunks. He seems very lonely... I walked to the door, about to knock, only ending up being brought to by darkness.
Transitioning like a boss
I woke up, tied to a chair in what seemed like a cave, I saw Annabeth there, staring at me with a sinister smile.
Y: Why?!
I said, feeling tears starting to form in my eyes.
A: Why? Pfft, please, you already know why.
She walked toward a rock, where a bottle of green fluid sat, with a syringe next to it.
A: Now, you made a serious mistake.
She picked up the syringe and started to fill it with the green fluid, while I tried to get out of the ropes tying me down.
A: You see, you took my Percy away from me, so now you will pay.
She flicked the syringe to get extra fluid off as she started to walk closer.
A: I was going to give you poison but I decided that you should get a fate worse than death it self.
Y: No! Please! I beg you! Stoop!!!
I kept at it, trying to get out, but it was no use.
A: This will make you so crazy that you will wish for death it self!
She laughed as she pinned my head against the chair and injected it into my system through my arm.
Transition....again
I woke up, to see a person in front of me, but there was no face. Nothing at all. I realized that a group of people were surrounding me. But, nothing, not a single face!
Wait....

Who am I?

OKAY! I feel like I should get this cleared up. I have only read Percy Jackson and the Olympians. That is the only series I have read but I will read the rest that connect with this story!!! Btw, who here likes BTS?
