you were Mash's roommate at the prestigious magic school. Even though he was an idiot, he was still nice in a way, even with his monotone tone and personally

one day, after Mash fought with Lance and got a silver coin, he was trying to count how many more coins would he need for a gold coin

"So if I have two... Than that means I need 28 more"

he said in his monotone tone, he got it wrong, of course
