Black Market Codpieces and Coats for Snowmen

As I once again do my fic-searching rounds for Kairi-centric corruption 'fic, and Nanowrimo Time comes around and I try to think of which fic I want to goddamn do, my mind turns back to corruption 'fic in general and something I have noticed in fuck near all of them.

*Note: Parts of this little bit of meta are Kingdom Hearts fandom-specific, though most of it applies to most fandoms, at least those I've observed. There aren't any spoilers for anything.

**Note 2: First and foremost, a very short definition on what corruption fic is. Basically, Corruption, or Anti-Redemption fic is a fic in which a good guy turns and goes to the evil side, for any reason, whether of their own will (for varying reasons) or by force (by various means). To me, a fic does not count as corruption if the person goes good again at the end of the fic.
The two terms will be used interchangeably in this little piece of meta.
