THIS IS NOT MY BOOK!!! I HAVE NOTHING TO DO WITH THIS BOOK!!!! The original book Twist and Shout by the author from achiveofourown (Gabriel (AO3)) ALL THE CREDITS GOES TO GABRIEL AND STANDBYME!!
Glitch is a teenage girl who lives in a horrible world with her horrible self. She thought everything was done, no more fun, no more anything. Until she found a boy, in a sheriff hat, and the most perfect blue eyes. They change each other in this disastrous world, and that's ,how they live now.
This is my take on what is going on Levi's mind during his encounter with the female titan and the death of his entire squad.
