At the least, it was top-tier animation.

I always have trouble approaching serious romance/courtship stories, because I feel there is a fine line between poignant, and pretentious. At the risk of over-hyping what is effectively 'First World Problem: The Movie', I much enjoyed this after I let myself get into it. At 49 or so minutes, the feature doesn't wear out its welcome, as these sort of endeavors often do without mood lighteners like comedy, fanservice, or... plot.

Fair characters, great animation, story substituted by introspective. Your mileage may vary.

Also, the version linked above is perfectly watchable, with only one typo/error In the subs I could tell, but be warned that the last short scene is not subbed (after the credits), though the remaining dialogue is easy enough to infer.

Recommended.
