In Hanasaku Iroha, who will Ohana end up with?

Now that the anime Hanasaku Iroha is about halfway through, I'm really getting into the series! I love Ohana-chan, I think she's adorable, and her story reminds me a lot of my own trials and tribulations as a fellow teenage girl. Things are heating up a little on the love triangle (quadrangle? lol) front, so I was wondering- who do you think she might end up with, Ko or Tohru? Please also give your reason why you think one way or other in your answer too, I'm really curious! Thanks ^_^
