Oh, I remember this one. The protagonists are all screwballs in their own ways, but overall it's actually quite charming.

Honourable mentions due for one of the supporting characters, for being a really great guy despite being relegated to serving in the beleaguered-tsukkomi role for most of the series.

I kinda want a spin-off for Satou-kun, but at the same time, I think this is a happy ending for him in its own way. They're like one big, happy screwball family.
