the world became crazy. The zombie apocalypse came. Everyone became crazy they would bite someone's neck so that the virus would go through their veins up to their mind.

Jungkook, was on the train. You both were strangers. Then the zombies bite someone and then.. it becomes crazy. He saw you getting tripped and he saved you.

"There's a little girl there! I'll save her!"

Jungkook shouted and grabbed the little girl with you and went to the other side of the train and locked the door.
