Camila/You - Saving you - Prologue

As I read this fic suggestion (Can someone please write a camila/you fic but like you meet during a zombie apocalypse when u save her or her sister with like little drama and a lot of action come on please !!!!) I told myself why the hell not!?
So this is about you and Camila, falling for each other when the whole is falling apart.... Of course things won't be easy. Read and you will see.
