(It's mostly that they're never used in fanfics. I'm thinking that yeah, I should (though almost more for Hakuba than Kaito--for all I know Aoko could be on the pill in the fic), but there's a lot I don't know about using them because they're never used in fics. Good for me to stretch my boundaries, though. ...I need an OT3 icon for those three, too.)

*is just way confused by that so just smiles and nods*
