What a bizarre little story, it feels like the whole thing was just a complete waste of time.
By the end of eighteen chapters, two entire volumes, the only thing that seems to have substantially changed between the first chapter and the last is that the lead girl Ibari is wearing an outfit a normal human would wear instead of the bizarre chuuni-ass zipper clown outfit she started with.
To be clear I don't mind when a story ends with the status quo, but the problem is that it's been the status quo the entire time. Yonekura knew he liked Ibari, she knew she liked him, people outside the two recognized they liked each other, and absolutely nothing of substance happened to their relationship the entire time. Nobody learns anything about themselves or each other - besides Ibari wearing normal clothes, which is definitely an improvement but not significant enough to carry a two volume manga. We even had a couple times where it looked like we'd almost have a story begin, but then it gets aborted almost immediately and we smooth back out to default.
I see people here saying the story got axed, but that would suggest there was a story to axe in the first place. To me this feels more like a oneshot that got extended to two whole volumes, but the author didn't have anything to fill those extra pages with so it just dragged its feet. Not offensively bad by any means, but there's just not much to talk about.
