This dorama is yet another example of how many Japanese masterpieces are out there, vastly ignored by the Western audience.
Now, since it's unsubbed, I've watched this by helping my little more than basic knowledge of Japanese with self-made machine-translated subs (nothing too complicated: you just take the Japanese subs, run them through a machine-translation site, and then retime them to the RAWs by removing the commercial breaks gaps).
And I'm so happy I did, 'cause this is the very definition of "hidden gem", seriously!

A marvelous script, mixing quirky and lovable characters with hilarious comedy elements and deeply humane moments.
A great performance by the main cast (kudos to all four of them! I wanted to watch it 'cause my beloved Moririn and Sakai Wakana are in it - the former is not only such a marvelous actress, but also at the top of her beauty in this; and the latter is always a pleasure to watch, period. But both Mikami Hiroshi and Toyohara Kosuke were *absolutely* great too! Well done, guys!).
Some *fantastic* music (some of the OST reminds a lot the best Goran Bregovic tunes from Kusturica's movies!), great direction/editing/photography complete the package.
Perfect 10!
