I have shared this with a couple people here and elsewhere. It is one of the few dramas I have watched that has actually tugged at me in ways I can't describe. It's a very sad romantic drama that had my girlfriend crying more than a theatre full of women watching Titanic for the first time. It's Japanese, and subtitled, and unfortunately on youtube where you have to click on the next parts. I'm no movie critic by far, but this is up there with the best I've ever watched.
For those into dramas... it all starts here:
