Love will tear us apart: Human! Betrayus x OC (AU)

(This was partially inspired by my original Betrayus x OC story, and me having seen the original 1977 Suspiria a few too many time.....)

Gather around, my child. For I have a tale to share.

But be warned, this isn't a fairy-story that you grew up with..... No, it is something darker, and more dangerous.

For even darkness blooms in the purest of hearts, blood stains the stones of hallowed halls, and sometimes love doesn't just require flowers.....

It requires thorns.
