Remember the episode where the 3rd is remembering all the generations of the Konoha ninjas, and then they come to the 4th hokage and his three students, it was kakashi, a girl, and another guy with goggles. The guy with the goggles was his best friend who was an uchiha, and that is the person who kakashi goes to the grave of every day, and that is the friend from whom he got his sharingan eye.
This picture of Kakashi and his two group mates is also shown when kakashi is on his bed in the hospital after fighting with Itachi. Its right beside his bed.
No, i have not read the manga, but im sure this is true. its so obvious.
and you do not know any of this since it has never been said ever. this is just pure speculation nothing else.
