This is more of a comedy than a romance, despite the title. The ML, Kuwano, is SO WEIRD, but it's great fun to watch his weirdness. His family and co-workers are fond of him despite it, help him out with the situations he gets into because of said weirdness, and hope that someone will come along and love him and sort him out. There are a few candidates for this: a nice doctor he meets, the nice manager in his office, and his neighbour, who has a dog called Ken that's probably the best character in the whole thing - Ken and Kuwano have a dog-mance which is utterly adorable. It's beautifully shot, laugh-out-loud funny and marvelously acted. I thoroughly enjoyed it and downloaded its cheery intro theme. If you're looking for something light and funny with no angst, this show is for you.

There's a sequel series - Mada Kekkon Dekinai Otoko, the man who still can't get married! - which is also pretty great, definitely worth watching if you liked the first one, and has (maybe!) a slightly more romantic end.
