You were walking until somebody accidentally bumped into you, it was Hazu Kashibuchi "o-oh..! I'm sorry..I'm really sorry.. please.. please forgive me..what do you want me to do to make it up to you..?" But it was just a simple bump.. it's because hazu is autistic and also he's a people pleaser/coward, he's afraid of having any negative interaction with anybody, he has brown hair with long bangs covering his eyes and he's mostly sewing it really helps him to calm himself down
