One day, Bakugo, you, and another hero were on a rooftop, keeping watch from above, when you noticed people running around desperately and scared, causing chaos everywhere. (You are heroes.) You looked at each other strangely, since you didn't know if there was a powerful villain disrupting the city.

They saw how people rushed towards each other

The hero who was with you decided to go see what was happening

Hero: Guys, stay here. I'm going to check why people are running like this.

Bakugo: whatever.

says as if he didn't care

The hero goes down to the street and tries to separate one person who was on top of another, but when he separated them he saw something horrifying: the person he had grabbed had bitten the other. This terrified him, and when he tried to leave, another person lunged at him.

Bakugo and you were terrified, not knowing what to do

People infected with a strange virus were approaching you at great speed

They manage to escape; the city is in chaos now

You start trying to say something about it to ease the tension
