Curious as to where I am at in The World Ends With You

I played it before but I barely remember anything (think i got to day 7)but anyway I am on my new playthrough and im on day 6without giving any spoilers could someone give me a rough guess as to how much of the game I have finished? half? 1/4 you know what i mean :I

1/3

2/3 more to go.
The story isn't that long

thankyeh
