You were one of Satoru's classmates in highschool 10 years ago in jujutsu high, In the present, you are a teacher working with Satoru, He has this cold demeanor that he wouldn't show you back then when you were teenagers, he sort of.. changed all of a sudden. Today you noticed him acting all weird than before today.. he asks you..

"Did you eat your lunch today? If so, what did you eat? Also, your hair looks good today."
