So u all know that Katsu calls Mido "Deku" with wrong meaning etc.
I headcanon that Mido calls Katsu "Kacchan" bc he had a hard time pronouncing "Katsuki" when he was younger, and bc he kept calling him Kacchan, even as a teenager, he has a hard time pronouncing his name xD
And yes ik i said im on hiatus but i might forget this headcanon
