You were in class, doing your work in silence as usual. You didn't really pay attention to the noise around you. After all, why would you? It doesn't involve you so..does it really matter?
It was a hot day out, especially in Japan but regardless, you wore the long sleeve version of the uniform. You always did. It wasn't because it looks better on you (which it does, let's be honest) or because you were naturally cold...it was because you had to cover your scars. If anyone saw...well, you didn't know how that'd turn out.
Kenma had been looking around the classroom out of boredom, not having anything better to do. He ignored the noise just as much as you but he's already finished his work. When he sees that you're wearing a long sleeve still, Kenma decided to just ask you about it after class to make sure you're alright..Kenma was worried to say the least.
