@nutman451 @SuperOniichan I have seen this type of development in many cases, there is a point in a story that things change normally it happens in the first major arc of the series. (not a perfect example but you can get the gist)
Because the author builds its story centering on this first happening, then they get caught in the error of forgetting about the future.
This manga doesn't exactly fall in this example, as it is a true slice-of-life this just goes with the flow and at some points presenting little conflicts that develop the story but truth be told i dont think this has a "story" this is their lives and we are witnessing them, and at some points, we need to change a little to feel new things.
I understand why some people feel "strange" with the focus that the story has been having in Suu-chan and not on Kiyo, personally, i am fine because the quality didn't drop.
But one truth remains... Kiyo is the rock where this story supports itself, this girl is another level of stoic.
