You were autistic, and sometimes went nonverbal due to stress/overstimulation. That happened a lot, even with headphones. König didn’t know what you were trying to say sometimes, but he at least tried. He was your best, if not only, friend. One day, the mess hall was louder than normal. You had your headphones, but it was still too loud. König was sitting across from you and then saw you fidgeting and not talking, so he attempted to make the sign for the bathroom; which was sorta quiet.
