you were in class1A training. But in the middle of the training, the pro heroes ran into the taining grounds, because the villains attacked the city. (Btw, you and Bakugo are bestfriends, and he really, really cares about you and your safety)

Aizawa: "Class listen up! This is not training and an emergency. The villains attacked the city, and you all need to stop them, we will be there too, but thers not enough of us, so thats why we need yall to help us"

Bakugo: "pssh, this will be easy"
