I meant to write it, but I keep finding some good reason not too 
Anyway, I guess I can write something quick.
First of all, I came in this knowing nothing about the plot. Mostly, it was a recommendation of @QuackingShoe, and that was good enough for me 
As I mentioned in some of the earlier threads, I first thought that the story would involve no supernatural element at all and would mostly deal with ハルヒ’s wacky hijinks. When stuff that should not be named happened to みくる, I further thoughts that I might not like said hijinks after all. Then plot happened.
It was a first shock to learn that it was, after all, a book involving supernatural elements. The thing that really got me, though, was the part where it turns out that ハルヒ is the creator god of that pocket universe. The fight scene with 朝倉 (I think?) was pretty good too.
I kept thinking about the place of キョン in that picture the whole time. It’s kinda convenient for him that he is at the best spot (from his point of view), the one he said he wanted at the very beginning. So much so that I’m half wondering if it isn’t his pocket universe, where he gets to experience everything from the sideline, plus having the attention of a woman he finds attractive (with additional eye candy).
That being said, when the end of the world got basically triggered when ハルヒ saw him a bit too close to another woman, I reconsidered that hypothesis. Maybe he was just meant to be happy with his spot, or maybe the creation of the pocket universe didn’t change the world so much, and it’s just really a happy coincidence.
Anyway, when everyone kept saying that his existence was “special” for ハルヒ, I absolutely thought that they would get together; it’s a bit of a cheap development, but heh, makes sense. Anyway, the fact that the kiss scene ended up being a “dream” allows the author to go into will-they-won’t-they territory despite development.
Sooo, overall, I’d say I liked it, but still, there were parts I wasn’t too happy about. If people wan’t to keep reading, I don’t mind going on, but I don’t think I would do it on my own.
