Uchiha's, they're all cool and indifferent and you can never truly understand them. Especially a certain Uchiha named Itachi. Although in Koinu's case, it's a bit different. She is the only one Itachi has ever truly opened up to, the only one he has told his deepest secrets to, and the only one besides his little otouto that he has truly loved. Too bad she's a wolf.
