would be hilarious if the glasses girl won.
I actually think she has the best chance. On reason being that she's not in the original trio. If any of Akira, Kanae or Shigure wins, it will sort of feel unfair for the other 2. If Sumika ends up being chosen, it's sort of fair (or maybe unfair?) for everyone.
Also she's Fumi-tan herself, though maybe that will end up biting her in the ass. I can see it clearly as day Kotaro saying that he could never date Fumi-tan because that would defile her, or because Fumi-tan belongs to everyone or some crap like that.
That said, my favorite is still that one from the part time job that only appeared for 1 or 2 chapters. lol
