Here you can request certain characters to have tourettes, or just tics for various reasons. You may request certain tics and scenarios that they happen in.Each oneshot happens in a separate universe unless otherwise said.
You can request a tic attack if you want.
(Since it seems those are popular)I automatically assume that the characters classmates know about the tics unless otherwise specified.
I do not assume that store employees and other random people know... because how would they unless your a famous pro hero, in which case you don't get privacy.
I hope you enjoy ♡
