Not even surprised this happened!

My otp:  Kanji and Naoto, though if you read my tumblr you knew that already  :)  
My most hated pairing:  I actually don’t have one for Naoto.  I’ve seen her in quite a few pairings, some that work, some that don’t, but there’s not an otp I hate for her. 
My unusual otp:  Yosuke/Naoto.  I even wrote a fic for them once.  Just… I dunno, I guess it’s the “idiot” of the group with the smart detective that gets me, I have a soft spot for supposedly stupid characters who end up with the smart one.  

As an added bonus, my hatetp (is that even a thing) is Adachi/Naoto.  Considering the fact that she came onto the scene like, “The police are idiots, they don’t see what’s right in front of them,” and is a woman, I was a bit disappointed that Adachi never had anything to say about that.

My crossover otp:  Light from Death Note and Naoto.  Don’t even ask how it happened.  
My brotp/friendship otp:  Rise and Naoto, hands down (with a bit of fooling around, maybe, I do dig the OT3 of Kanji, Rise, and Naoto).  All those fics where Rise gives Kanji and Naoto that push towards each other?  Totally, totally see that happening.  

Added bonus brotp is Souji/Naoto, and hell, maybe they did a little something, too, actually I have a headcanon idea to write for that at some point.  I think Souji is logical enough to give her good advice in matters she doesn’t want to address (aka her feelings for Kanji).  Rise is blunt and straight to the point, but I think Souji could actually sit with her and be like, “Look Naoto, that boy cares about you.” 
Character headcanon:  I’ve written a ton, take your pick  :)
