I think he’d try to be secretive about it. He’s used to being the only one to care for himself (and even that isn’t optimal, he’s not his favorite person in the world) so he wouldn’t make a big deal out of it. He’d probably curl up in his bed and let out soft whimpers, feeling feverish but not wanting to bother anyone with his problems.
GAH! that’s too sad! what about when his s/o finds him like that? *sad seal eyes* @emmcfrxst
