You were a teacher at Kimetsu Academy and you often got along with the math teacher who had slight anger issues but he did have a soft spot for women, little kids and you so you were pretty lucky

He went to your house to grade some papers but as he looked at the work the students did he just started complaining about them even if you had work to do you listened to him complain

"These kids work like preschoolers! They don't even show any work! How do you even deal with these children!?"
