I actually really like the slice of life happening bc I think the characters deserve it. But I also understand why some people feel like the story’s changed. It’s not personal, it’s just about not judging others for their opinions, there’s no need to tell people if they should or shouldn’t keep reading.
I think it’s because people have been reading since the beginning so they still want to see how it ends even if they’re not feeling the story anymore. And probably some people are hoping the story develops in a way where they can start enjoying again. I understand your POV too though, it can be frustrating to see people constantly complaining instead of having positive discussions.

For all of those who don’t like it, please stop reading. Just because you had set an expectation, doesn’t mean it’s gone bad. I frankly think it’s has a very good flow of things.
