I must give credit for the inspiration behind this story to a fellow member of a Facebook Heartstopper group, who commented on something I wrote there about imagining that the teacher's MUST have discussed Charlie and Nick between themselves at some point, unseen by the rest of us. In fact I'd written the basis of this story within an hour and have spent some time refining it ever since.
All credit to Alice Oseman for creating the wonderful world of Heartstopper and all the great characters who exist in it.
Please note: Mr. Ajayi's first name is in the Heartstopper cannon as Nathan, so obviously I've used that, however as neither Ms. Singh or Mr. Lange have their first names mentioned (as far as I know) I've used the actors' real names instead, so they are Chetna Singh and Alan Lange. In addition, according to Alice Oseman's list of characters although the pupils at Truham call Ms. Singh "Mrs Singh" her actual name is Singh Stevens, presumably a hyphenated combination of her and her wife's surnames. I've created back stories for them which may contradict events I've not yet noticed without a further re-read of the books.
