永沢君たちって、...なんていうかジメジメしてるところが怒られるもとになってるでしょ?
As for Nakasawa's crew,...how do I put it? Their gloominess becomes the source of them getting told off. Right? (my best-guess translation)
I thought してるところ was "in the middle of doing", but I can't get the sentence to work with that translation. "The source of being told off is 'in the middle of'/while/during being gloomy"? The implication seems to be that they only get told off when they are gloomy.
Have I totally messed up the overall translation? Could you please clarify how ところ is working here? Many thanks.
