The pacing is insane. Looking at the other stories, Hanako's is about 4-5 weeks(?), with Lilly, Rin, and Emi around nine. Shizune's is something crazy like 9 months because of the timeskip to graduation, but I digress. The point is that 4 acts taking place in the matter of a few days is just too quick for my tastes. I don't really have a grasp on who Neko is as a person (whether this is due to my poor reading ability or not is open to debate) nor Miki. Hisao seems very deeply involved with her in less than a week; that I don't really understand. At this point, they should still be getting a grasp on the fact that they are now a couple, rather than rutting like rabbits and considering threeways with Miki Miura.
The story seems, er, not inconsistent per say, but rather unbalanced. Lots of dialogue with minimal backdrop description. This also includes lots of moving around and comparatively little insight into character thought process (for my tastes, at any rate). One thing I must say I dislike is the whole ten paragraph scene thing. Chopping writing up like that and tossing the reader around makes it hard to follow. Maybe try, as others have suggested, fleshing the scenes out more and add more backdrop to better understand what is going on where with who and why.
Now, what I really did like was the story. The topic was very fresh and new and came with a new author and writing style which I enjoy (sans the 10 paragraph scene thing). The main love interest was very alluring in her own way, but the way the leg was described was fairly grotesque. As for the technical jargon, that is something that I enjoy reading. While I don't really like being totally lost in a sea of acronyms and slanguage, I can appreciate diving headfirst into a hobby and getting more acquainted with meanings, adding immersion to the way Hisao was introduced.
All in all, I enjoyed it enough to keep me reading to the end and I wouldn't mind seeing the other two options
