Noctis has chronic fatigue (or some similar disorder like narcolepsy or fibromyalgia, its up to you) and Regis ends up hiring hiring him a caretaker because its become incredibly obvious Noctis no longer has the energy to take care of himself ( not that he was particularly good at it in the first place, I think we all remember his apartment in brotherhood). Noctis of fucking course he's fine and can take care himself and he's just a little tired sometimes (all the time) and he almost never passes out from exhaustion anymore and even uses the wheelchair now whem he has to and basicly being the big brat we all know and love

And then Noctis and Ignis meet and hey're both like "Oh fuck he's hot."

Srsly I will fucking love forever if anyone fills this for me -CFS has been kicking my ass and I need to see someone else suffer instead.
