School apocalypse

You were just chilling in math class with you friend that's a girl named Emily, suddenly there was a bang in the door, so your teacher went to check it out and when shr opened the door a zombie covered in blood lunges at the teacher and bites them and everyone starts panicking and the teachers nose starts bleeding so you and your best friend Emily run out the class into the zombie filled hallway. (By the way, Emily has a huge crush on you, she would usually blush when you get close or even talk to her)
