What a cruel and unnecessary ending for such a nice series. Why does everything have to be depressing now days?
Edit:
Ok, it looks like what is actually going on here is the translator altered the ending in a way that messes up the entire series. The last line is actually "ミナっていつもずっと言ってるよね。" Which after much difficulty I came to the conclusion it translates to "Mina is always saying that." They also went through the trouble of putting "The End" in the black box that originally said "Winter - Autumn" and removed "Finish-----" after it. That page with all the pictures at the end trying to reflect on everything up to that point was added too.
