A lot of the comments here really reflect my feelings on this manga, it started out as a silly gag manga that was sort of enjoyable even without expecting any serious progress, but by this point it is just painful to read. The constant state of emotional limbo makes Hishikawa look increasingly pathetic to the point that it just feels mean to laugh at her antics. On the flipside, Komaki just feels cold and honestly cruel.
I think the comedic dynamic has just been overplayed by this point and there would need to be some sort of shake-up in their relationship. Even if they don't get together (which judging by everything they never will), there needs to be a new joke besides Hishikawa makes an advance and is shut down. This is particularly aggravated by some of her advances being not at all ridiculous and over the top, which makes me wonder what the author is even thinking.
