>>30357244Mori's great at showing respect, but can't banter with JP Senpai easily (see Coco), but is much more comfortable being cheeky with Kohai, so it's a mixed bag.
What you find annoying is her opening up and being comfortable with her audience and among genuine friends, like her banter with Gura here. While that's not everyone's cup of tea, I love the Gap, and it makes her all the more endearing to me.
