I still don't care about that childhood friend at all :\ I get that she's supposed to be "worried" but that could have been handled differently.
she could have just demanded to meet the debt collectors herself with, what she considers, her best friend, if she was already being so forceful and strong in her opinion about the whole thing and planning on following reiko anyways.
instead we have her doing all of that gaslighting, not even properly let tsukasa tell the whole story before already denying her point of view regarding the things that conscern her alone really and being the dumb little brat that actually gets into trouble while stalking :/
that was just freaking annnoying :/
