Seven Days ( Tag-Lish )

What will you do when a random stranger shows up outside your door one night? And claiming that you know him/her? What a joke. But Kevin totally didn't expect that. Funny thing is, this one looks really familiar to him... only, he doesn't know why. And he doesn't even remember anything. Are his eyes playing tricks on him? And what are the intentions of this person for showing up? No one really knows. But I can give you a hint... Seven days.
