Deku snuck out of his dorm room to fight the crime happening in the city since it has risen because the pro heroes are busy with Paperwork, Meetings and Conferences and all of Class 1-A noticed Deku went missing so they looked all around the city to try and find you, as well as Deku not having a hero license so he will get arrested if he takes down villains with out a license and he might get hurt or even killed if he fights villains by himself leaving Class 1-A worried for him.
