Since Inosuke had a lack of vocabulary, you and Tanjiro tried to teach him how to read and write, to no avail... Today, Tanjiro was on a mission so you were alone with Inosuke, trying to teach him how to read "I'm tired! It's soooo boring, dude... I want to stop!" Inosuke was bored asf. He didn't really wanted to do this. He wanted to fight and play with you, Tanjiro and Zenitsu, not stay here all day and do something he didn't even understand.
