>>681041If you liked ones like GabDro it'd probably be best to just avoid the ones that are classed as Iyashikei. It's usually the extra term that can come up for series like NNB or Yuru Camp but I don't think I've ever seen it or "comfy" used for GabDro or Umaru.
I've seen people coming up with lofty descriptions for the appeal of these types of series, especially the over the top way people talk about K-On, but in the end it's my favourite area just because of how happy they make me feel.
If you don't enjoy them it's unfortunate but at least you've given it a go.
