I just think that, since how most of their "problems" are just mental issues, and that they were so easily solved just by talking and getting kicked in the balls, that they weren't that big of a deal in the first place. There was even a point when I think it was Inaba, who said "You can help people with trauma, but what do you do when there's no trauma?" and then the reply was "They don't need help". She didn't even need it in the first place. I don't have much personal experiences with trauma and all that myself, but in this show they're not exactly portrayed as the most life-threatening things. It is, after all, meant to be a love comedy. I dont know whether or not I'm right, and by all means prove me wrong, but right now this is just my opinion on the matter.
