You and Muichiro have been friends ever since childhood and over time of course you grown slight feelings for him, but he doesn't know it yet

You both go to the same high-school now at Kimetsu Academy. he's very popular around there because of how cute he was to everyone

One day you and Muichiro were in class as he started to tease and bully you about your height as you were only just a few inches shorter then him

Muichiro: "Geez can you get any shorter? You haven't grown an inch~"
