timeless love~[Mysta Rias x Reader]

This is kind of obviously an x reader fanfic, you will use they/them pronounce in this without any gender confirmed so everyone can read this and feel as comfy as possible, your name will be y/n (meaning literally your name lol). Another thing is, this is fully my AU and Obviously the only thing that belongs to me is the plot. (mysta rias is a vtuber from nijisanji En, he streams on YouTube and he obviously doesn't belong to me, please be respectful and if he says he's uncomfy with any FF about him ill delete this)

Another disclaimer: this is my first time writing and actually opening the FF I wrote so please be respectful, I do apriciate criticism as long as it's not purely rude, also be nice to mysta if you check him out.

Possible Tw's might be depression, swearing, cutting and anything in that way, not sure if I'll do anything like that but it would be easier for me to write that then just purely happy things :)
