au- Zombie Apocalypse

you were on the school's rooftop, with a guy that randomly bumped into you when you ran from the zombies who were chasing you and making you fall down but yeah, he helped you since you weren't infected like him and brought you to the rooftops because that's the safest place

he ties a bandage around your leg wound that he caused when he bumped into you

"So... What's your name?"
