This couple of chapters have been about teasing us readers
I was about to say exactly the same thing, though more about this last one than the Kaoru/Mask one, just because I'm not super into that pairing personally. But even then, at least those two had an interaction at the end, AND that was just a short- this chapter (a full chapter evidently) especially, I don't think they even talked to each other, lol.
I'm not usually one to criticize the writer or anything, and I'm still not really, but it IS a bit frustrating to see my favorite pairing in the tags and then just get like...imagine spots and no actual relationship progression or even real interaction.
