A perfect story in virtually every way. Hell, it is perfect but I don't want to seem like a blind fangirl or anything.
To enjoy this anime you need to be a fan of unrequited love and realistic portrayals of it. It's a very understated story, one that does not have a happy ending, nor does it have a bad one. When I think about it, your outlook on life will be the judge as to whether or not this ended on a silently tragic note or with a silver lining.
It's also very straight-forward, as most things are with a oneshot story that is also slice of life.
Noriko has returned from America and returned her hometown with her four-year-old son Mikoto. The question as to whether she'll stay indefinitely or try to remake her life is left vague but in her situation it is understandable. Motoki was an absolutely charming, sweet boy.
All of the characters in general were actual people and the narrative is as true-to-life as humanly possible given the subject material, which can either be refreshing in its realism or banal to people who want to see *something* else other than actual people being..people.
I woud recommend this as a palate cleanser if you feel completely dulled by ninjas, magicians, knights, pirates, or vampires and need something grounded in reality before returning to the more fantastical genres.
