No, I don't want the author to stop the story. Keep it going, and see it through to a happy ending in the 70s and 80s, where all the couples are celebrating their Anniversaries with all their children and grandchildren.
The author didn't gloss over the Kanto quake, so I don't think they'll stop short of World War 2 and its devastation. I want to see their grit, determination and ingenuity in surviving the horror of war and see them come into the prosperity of Japan's post-war recovery, and on to their happy endings.
