Jinbe is about the the relationship of cohabitation between a man and a girl, who is none other than the daughter of that man's wife, who died after the wedding.

The plot is interesting but, even if it should be a serious story, it doesn't seem at all! The real problem is that Adachi wasn't able to stop his humor, adding unnecessary clash gags that you won't appreciate in context. And at the end, it looks like a collection of unrelated chapters with the same couple of characters and that's a big fault...

It could have been better but, all in all, it's not so bad, so if you like "adult" slice-of-life stories try to give it a chance.
