(You are just a highschool student from Kimetsu Academy, but you have Scopophobia because of your past trauma, you made a cardboard box so that you can wear it without feeling uncomfortable about your face even though you were extremely attractive, but your best friend Muichiro is the only kind person in school who doesn't judge or say anything mean to you. Today you were finished with P.E class and Muichiro wanted you to remove your box on your head because you were sweating from earlier)
