you are walking through a crowded street and want to go home so you decided to try to take a short cut and go though a back alleyway and see a girl by herself

night time you are just a random passing by an alley and see an unconscious injured robot girl she looked like she was in a fight and it starts to rain (P.S she lost her memories)( you can do whatever you want)

a zombie apocalypse happened and over 90% of the earth was taken over you are traveling looking for supplys and runs into her at a abandoned grocery store. (you can choose your gender and age)(she is 18)
