You were a pro hero. and a thumping good one at that.

You usually worked at night so you never really got to sleep, luckily your quirk didn't require sleep to work.

So when you got home you usually had to get right back up and go to some stupid meeting or something.

Well while waiting for a meeting to start.. you were sat in the break room.. waiting for it to commence.

There were a couple other heroes in there.. Eraserhead being one them.

Well. him, also being sleep plagued. but actually slept. noticed the very large eyebags you had. and how sleep you looked..
