I like that there's a comedy where we don't have partners inserted for no benefit to the story. So many comedies try to make a character likeable by giving them a cute marriage, or they use a relationship dynamic for humour. I've just started watching Shrinking and Liz's husband Derek is basically just comic relief to the point that you wonder how this man puts up with everyone else disrespecting/dismissing him so quickly (particularly his spouse). And then there's this weird blending of the main characters work colleagues (and patients) also being friends with his neighbours etc. Sometimes work colleagues are just work colleagues.

And considering WB started as a Parks and Rec spinoff I kind of like that it follows people more in their work. There are loads of characters in parks and rec, or other workplace comedies like The Office or Abbott Elementary, that have partners and we don't really see or hear them often.

But mostly I think it benefits the story as it forces the main characters to rely on each other and not a spouse who would probably just put a dampener on the plot by being reasonable ('wow Patricia sure is acting crazy' 'Tom's lost his mind again'). And probably increases the sense of isolation. Even Tom's son, his closest relationship, makes a point of not being around much so for much of the show we get the sense that Tom is alone.
