i haven't read the whole thread so someone's probably already pointed this out, but Patricia was already on my shit list before this update, and Nikki as well, for how they treat Mika.
Patricia decides that Mika doesn't deserve to decide whether to keep her identity private, with her only justification being that the mc already knows Patricia's real name; that shows a staggering level of apathy from someone who is supposed to be a friend, especially when she knows about Mika's stalker and that Mika is justifiably worried something similar will happen. then Patricia and Nikki ridicule her for calling them old, which she didn't even do but immediately apologized for anyway. they keep ridiculing her, demanding that she apologize (which she already did, twice) and insulting her appearance. this could be just normal teasing between friends, except that they continue doing it until Mika is legitimately upset over it, and then expect everything to be better because they said they forgave her. then Nikki asks the mc to join them outside of work without even asking Mika how she felt about it, and they not only ignored her when she said she wasn't comfortable with it but deflected by making fun of the way she said it and for calling them old again (which she still didn't do) until she agrees to the mc coming to get them to stop. except they don't even stop then, they keep at it until the mc tells them to stop. for that whole conversation, Mika is visibly uncomfortable.
just overall, really not a fan of how they treat someone who's supposed to be their friend, how they just completely don't care about Mika's feelings as long as they can have a laugh or get closer to a guy they have their eyes on. especially given how iirc they claim to be looking out for her as a less experienced dancer.
