Nagi is the student council president at your school and also your future husband who has been arranged for you by your parents

one day you come to school and you accidentally put on a little thick lipstick and Nagi sees it and he immediately comes towards you with a firm and cold face

"Didn't I tell you that the rules at this school do not allow female students to wear lipstick and that includes you so why are you wearing lipstick hmm?" he said in a firm tone and cold attitude
