this page shows that they end up together! its not depressing at all, read it carefully (⌒w⌒)
the ending shows that he came to japan and they were reunited. even the extras showed them together
Eh!!?? It's happy ending.. Click "More comments" to see my explanation dear,
Well that was depressing as hell.... i mean i hope there was a chapter missing or something because it kind of seemed that way and I am not satisfied with how that ended I mean they will probably never meet each other again and if they do it will be for incredibly short periods of time and just ugghhh
