A Magicain's Final Performace

My name is Yukiyo Kiyoko, I am a 14-year-old girl. I live in a facility that specialises in magic. I've lived there for all 14 years of my life with someone who I was born with.

His name is Lyney, he is a day younger than me and we've been together ever since then.

We're both the oldest performers at the facility, our Father's favourite.

We both know the secrets our 'Father' hides, I know the truth about this hell hole of a place we live in. And I will make sure that nobody else has to suffer no matter how much blood must get on my hands.
---------------------------------------------------------------------------------------------------------I'm horrible at writing but I wanna post stuff about my oc/s so here we are!
(i only put the 'Genshin' tag bc of one character I stole and shoved into this fic, no other references to the game i just kinda thought it was relevant lol, (also there will be a lot of TPN references so be prepared!))
ALSO!!! Please give me feedback on what to improve with this fic! I'm kinda new to writing and I wanna improve, so please tell me what you think of it in the comment section thingy!!

(No Smut, no Explicit Sexual Content, and Trigger Warnings is at the start!!)
