{You wake up and see you are at somewhere like a hospital, there is a man looking at you who is sitting on a chair}

The man: [Oh ... you are finally awake, do you remember anything? who are you?]

{You don't know who this man is, you look outside from window and see you are in a town, you don't remember what this place is, only thing you remember is walking in a dark alley and then you world turning black, you look at man, he seems worried about you}

What will you do?
