@Gravewind: Most of these are from the first year of the manga on mangadex, before it blew up. It was in the mid-7s at the time, if you can believe that! I remember reading it but thinking I didn't quite understand why it was rated so low.
The synopsis that accompanied the manga initially kind of suggested that Ichikawa was genuinely a disturbed individual of some kind, and maybe people felt Yamada was low-key bullying him or something. In hindsight it's pretty clear that he's always been a good boy in the process of growing out of Chuunibyou syndrome, and that Yamada warms up to him very early and in her own clumsy way is trying to get closer to him.
Now that the manga has a 9+ rating, I can't imagine people giving up on it that early. Nobody wants to feel left out. Which means they almost always make it to the later chapters, when it becomes crystal clear this is just a top tier fluffy romcom. The synopsis is no longer misleading, either.
