Well... this whole thing didn't make any sense whatsoever...
There's really no apparent reason why everyone seems to hate the Kido guy. Well, up until the panty sniffing scene happens, at which point, I kind of lost all sympathy for him. It was pretty obvious that if pink slut didn't call blue slut's phone, he'd have either jizzed in his pants right then and there, or started masturbating.
Granted, the rest of the class isn't much more sane by any stretch of the imagination... but I suspect that the story was trying to imply that he was doing creepy stuff like that even before they deliberately baited him.
The fact that he could somehow recognize blue slut's scent seems to imply some things too. I have a pretty good nose, and it was even better back in high school... but I'm pretty sure I wouldn't have been able to identify someone by scent. Not without finding ways to get exposed to said scent beforehand... which has unfortunate implications for the guy.
It definitely makes it seem like he'd outright stalked Aoi, but the story doesn't seem to want to commit to... anything really except everyone in said story being horrible people.
Oh well, the girls are hot and the scenes weren't bad, so not a terrible way to waste some time... but definitely not a VN I'd recommend to anyone for anything at all.
