For Sakura, before she was twelve years old, her fantasy object had always been Sasuke, who had just defected from the village and conformed to Konoha's public aesthetics.
For Kakashi, before the age of thirty, he had no interest in women at all, and of course, he was not interested in men either.
The only woman who interested him was dead, and the only man who was interested in him was also dead. As a result, he had no living beings to talk to, which caused Kakashi to spend a long time in isolation in the future.
