(I can't believe some idiot on the last page actually pretended this story was anywhere close to the worst stuff on this site. Redirect all your complaints to Oshikko Sensei please. lol, Jesus Christ.)
This also, but not sure how it is in comparison with Oshikko Sensei (never read it)
Ahaha I think the reason why this one-shot blew up instead of those two is because this is a lot tamer thus there is a wider audience. The sex is only at the end so people can read through, skip the sex and still get the general storyline. With Flower Picking and Oshikko Sensei, people can pretty much tell right away if they'll hate it, so they then stop reading and flush it away from their memory. I've read a lot of fucked up shit and man, Oshikko Sensei definitely is among the top. I still can't believe I read all the chapters of that...I don't think I'll ever get used to urethra play....
I feel like "In the Rain and Cold" wasn't trying to be as controversial and tried to create a plot (a horribly written one), while the other two were obviously written for the lolicon sex. When it's just porn, people don't care as much, but if there is even a hint of a storyline, people begin to take it "seriously".
In case someone misunderstands, I'm not saying people shouldn't be discussing real life issues that come up in a stupid manga. I think it's great and please carry on. These are just my thoughts on why this one has a whopping 80+ comments vs the other ones mentioned :)
