If you liked very touching stories filled with love, like Clannad ~After Story~. Then Hanbu no Tsuki ga Noboru Sora would make it as another ideal anime that you should watch! Unlike Clannad ~After Story~, it's straight to the point without dragging it too long, explaining the short 6 episodes of the anime itself. A great short story!
Both are really sad in the romantic and dramatic way....
If you like Romance and drama with some heartbreaking moments, you'll like this one!
Dissimilarity: Clannad after story is the second season in The Clannad serie (suggest to watch both seasons though first season isn't very sad) while HnTgNS is only one season with 6 episodes while The Clannad serie keeps over 20 episodes each season.
