It takes a special kind of anime to make a line like "then they had a lot of sex" to actually sound cute and wholesome. The second season expands on the story of the first, with more vignettes set in the past and back stories for other characters like the otaku husbands little brother and the office lady wife's friend. Despite all the challenges, this couple with mismatched personalities is committed to understanding each other. The series is a perfect example of Japanese "was" or social harmony between all the different characters. Of course they both have their insecurities, but they take the time toalways talk things out, and make things work.
