Well... I finally got through all the chapters.
And honestly... there was one main reason I did so: To defend Best Girl Reiko against the heretics.
The manga itself though... it never goes anywhere. There is no overarcing plot. At most there are only a few continuity nods. The whole damned thing is just an unending stream of tiny 8-page chapters with self-contained microplots. It actually goes through 3 years without anyone actually advancing a school year, graduating or anything. Suspension of disbelief on that level is nigh impossible.
And while some of the characters are at least interesting, the fact that nothing ever changes results in a gradual loss of interest over time.
Essentially it might as well have just been an art book as it contains almost 200 chapters of basically nothing happening. The only entertainment value is in the lewd shots. That is it.
Bad Manga. 4/10.
