While I do agree that the whole "person suddenly appears, girl sees their love interest hanging out with them, misunderstanding ensues" plot this seems to be going for is tiring, I'm honestly more intrigued by Kurokawa's behavior towards Fujishiro. We haven't gotten much perspective from her yet, and now that we do it's coming across a little obsessive and creepy.
And judging by the comments on this aspect of the chapter, many people seem to be of the mindset "it's not what I was expecting, therefore it's bad writing." Even though, as someone pointed out earlier, this didn't exactly come out of nowhere...

As for both of these developments, I think Ajiichi has garnered enough trust from me as a writer so far, both from this story and Dear My Teacher, to have me reserve my judgement until things finish playing out.
