It's unchallenging, warm and nice. I don't know if I'll ever rewatch it, but I enjoyed it.
It also has a not-too-bad portrayal of its historical period (early 1920s Japan). Our heroes are usually tucked away in a village, but occasionally they'll go into town and we're reminded of the era's cars and clothes.
It's a romance between two sensitive maidens, one of whom is male. Yuzuki Tachibana is the show's catalyst, although Tamahiko Shima is the viewpoint character. Yuzu is a short, optimistic ray of human sunshine. She's so irrepressibly nice that she transforms everyone she meets, even though she's been sold into marriage at the age of fourteen to pay off her uncle's debts. Her husband-to-be, Tamahiko, is a man she's never met and a declared pessimist who wallows in his own misery and thinks everyone hates him. He lost his mother and the use of his right hand in a car accident, after which his borderline evil father declared him to be useless and sent him away for ever.
Yuzu decides that Tamahiko's a gentleman and thinks she was lucky to be given to him. What's more, her optimism becomes a self-fulfilling prophecy. Despite appearances, Tamahiko isn't actually a self-obsessed grinch. He's just sensitive... and, in fairness, life's not been nice to him so far. (He's from a rich family and he's financially comfortable, but that hasn't helped him.)
They're the main characters, but there are others. Tamahiko has a little sister who shares some of their father's more off-putting traits, but might actually be nice underneath. If you give her a push. Then there's Ryou, a girl from the village who's purring, catlike trouble on legs.
The show's nice. It's basically a happy warm fuzzy wish-fulfilment anime, but occasional episodes have enough teeth to avoid the charge of "saccharine". The damaged people Yuzu meets are pretty extreme in their early appearances, while the last few episodes feature the 1923 Great Kantou earthquake. (The anime's depiction of the destruction is accurate, although we only see the aftermath rather than the carnage itself.) Also, Tamahiko has some communications issues to work through, some of which (e.g. eps.5-6) backfire badly. Some of the high-and-mighty male attitudes that are being shown by reflection here are unpleasant, e.g. some appalling fathers.
Overall, though, the show's fluffy and relaxing. I liked it.
