I finished a while ago and I finally have come to terms with the ending.
I have read it essentially from the beginning and of course all that I expected of it was goofy ecchi shit and at least it delivered on that. The story at first was actually quite interesting and I had actually sorta enjoyed the manga for the plot while of course the "plot" was still amazing. After a while though the story started to feel less exciting and interesting. As the scale of the problems and supposedly the stakes got bigger the less interesting it became for me. I was reading it weekly though so it wasn't really a burden to read a chapter a week so I stayed. The last arc was kind of bland that I didn't even realize until the last few chapters that it was the end.
I don't really mind the ending per se but I think that the reasoning for (you know) was kinda bs at least in my opinion. I expected that that was how the ending was going to be and so did a lot of the people who read this. But I at least though that there was going to be a good reason for it.
Overall though for what it is, it is a pretty decent manga with a pretty decent plot and of course the amazing "plot". I never really feel bored when reading. Tbh through I just like it for the fan service it's not the worst story but the story isn't really my cup of tea.
