maybe an au where they teach in a high school or something, and harry is the new teacher and maybe like one of the old directors made a mistake and said the new maths teacher is named Harold and should start today and everyone is making jokes and expecting like an ancient but then harry arrives and louis is so overwhelmed because that’s not an old man, but a hot, super cute and clumsy math genius of a man so louis keeps finding ridiculous excuses to talk to him like what’s 2+2

“WHAT’S 2+2″ JSHDFLJSHLFKHSF me with my crush definitely

“harry i need help grading papers” 

“uh, sure”

“can’t decide if i should give this person an 89 or a 90″

“….uh, i don’t know, why are you asking me”

“youre a maths teacher, youre definitely more adept with numbers than i am, so 89 or 90?”

“louis this is an essay”
