EDIT: The title should actually read: "Need help finding a Japanese love film (vague description)"
Before anything, I just want to say sorry for the very vague description I'm about to give of the film! Anyway, on my way back from Japan (arrived home yesterday) I was on the aeroplane and came across a Japanese love story whilst flicking through the films available. I used 'Air France' to travel if that helps at all. I only got to see like 3 minutes or so of it as it was right at the end of the flight that I saw it! And it didn't have its title
... it just said 'Original Version' or something like that in loads of languages, I'm pretty sure this isn't the name of the film as I searched for it with nothing of the sort coming up.
Anyway, on with the description. I believe it is about a teenage love, the girl is a rocker, and does concerts (I believe!!) and she before leaving to go somewhere, a boy rushes to the terminal and calls her, and then shouts to her in English "I love you!"... she replies "say it in Japanese!" and so he does... and a bit later after the interruption from the stewardess... she gives a concert which turns out to be very successful and they celebrate afterwards, and then I THINK the owner of the bar or says something like "quit your jobs and work here! I'll pay you 40,000 yen a month!" (I'm not sure if that was the amount of money :P) and then one of the band members replies "is that it!?"...
that is about all I caught, again, apologies for bad description, and quotes aren't exact, but very similar I believe! Any help would be very much appreciated!
