These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Horror: That catfight that happens in episode 3 while the students are planting rice in the field, and then gets everyone splattered by that stuff? The field is filled with water, and they are also trudging through knee-deep mud and manure (for fertilization) as they're planting. So the fact that the two girls weren't wearing much, and then get tossed around in that water/mud, means they probably had to shower for quite a long time to get all that stuff and stench off. And hopefully none of them accidentally swallowed or inhaled that water...
One of the Forestry Department members describes Minori as "pudgy" in episode 5 (to which she doesn't even bat an eyelash), but one would be hard pressed to notice it other than her impressive chest and rear.
This might be because she's often standing next to Ringo, who is a former model and thus, quite thin.
Then in episode 7, she, along with Ringo, Kousaku, and Kei, all become much chubbier due to Minori making too much food. They lose it a few scenes later, but not before Kousaku pokes fun at Minori for being the last to lose the weight, and accidentally sends a picture of her to her parents.
