Alright I'm not updating the fic anymore. The major reason being my English, I'm unable to express what I write in this language as well as I want to. So sorry :-( But I've decided to tell a summary of how I had intended to proceed it, as I've always felt that the least the writers who abandon their fics could do is tell the summary of the remaining story to their loyal readers.
On to the summary.
This fic was meant to be a buddy fic of Kisame/Itachi foremost, with a heavy dose of Sasuke/Itachi brotherly relation along with the bitter father son relation with Fugako. So it was meant to run on its theme, characters relations and motivations more than the plot which was something like this.
Orochimaru, a crazy genius, was friends with Fugako & Mikato from all their university days. He also happen to have a crush on Mikato which was more due to the fact that she was as bit as genius as him if not more, and Oro felt they would do world a favor with getting together and conceiving a superior genes child as he thought to believe. Mikato however fell in love with Fugako and married him leaving Oro bitter.
Many years passed Oro succeeded in whatever he tried and through one of his business met Fugako. This coincidence meeting sparked the old rivalry flames and he began using his manipulation skills and social relations & standing to doom Fugako's business. Fugako ended in debts, strained business relations and all around failures which led to family conflicts with Mikato. And in fit of rage one day he had a fight which result in Mikato dying by a couple gun shots; which to this date is a questionable as to who fired, Itachi or Fukago or Mikato herself as they all had been trying to wrestle the gun from Fugako's hands at the same time.
As expected the family fell apart just as Oro had wanted. A year more and finally Itachi, proving to be Mikato's son, took over business improving it, and caught eyes of Oro. Not being able to stand Itachi restoring the family to better position and jealous of Fugako's having a son he should have had, Orochiamru got him kidnapped.
So this is how Kisame entered the picture, he was a low class, jerk with a gold heart, goon who used to do only minor criminal activities to meet ends, but when Oro hired him to kidnap Itachi, the huge money sum made him accept the offer.
The main story was meant to focus on Itachi and Kisame slowly developing trust and understanding, with Kisame finally helping Itachi escape and make Oro pay.
There were elaborated scenes planned for Kisame's introduction, Itachi's kidnapping, captivity, escape, Itachi's worry over Sasuke and vice versa; with a few cameo: Kakashi as manager of library where Itachi worked part time and all of Akatsuki as criminal organization hired by Orochimaru.
The fic was to end with Fugako dying, but redeeming himself by taking Oro with him to protect his children, Itachi forgiving Fugako, living in peace with his younger brother and Kisame leaving his criminal ways. Ta Da!
If you have any questions, wants to overtake the fic to continue story feel free to ask. And I'm again so so so sorry not being able to continue. :=(
