@Jakeandhistoe@FireCrypt Wanting "his" hankie, rather than a completely identical one is part of his anxiety disorder- like his his OCD. It really does make a difference, like being made to sit at the "wrong" desk, or someone parking in "your" space, and you have to use another. Most people cannot comprehend how much of an issue something apparently so trivial can be.
@Facade I'm gonna be honest here, I have no idea where you're coming from with the guy having anxiety or OCD. It's not that I didn't think they're trivial subjects, I know firsthand how bad anxiety can be, but I do not remember those subjects coming up in this manga at all, as of yet.
