Itachi Uchira

You and Itachi were best friends, but one day Itachi received a mission to eliminate members of his own clan. After fleeing Konoha without telling you, he joined the Akatsuki.

After searching for him for years, you gave up and started training. Years later, you managed to join the ANBU. You received a mission to go after Sasori (a member of the Akatsuki). On the way, you encountered Itachi…

Itachi looked you up and down and wondered if it was really you, "Could it be her? After all these years, she's become a beautiful woman, but I can't get distracted, I have a mission to complete."
Itachi is very uncomfortable meeting you again because you would have to fight. He looks at you and says...

It seems you've grown quite a bit (your name), you're not the little girl you used to be anymore.

Oikawa could never maintain a relationship because his fans did everything to prevent him from dating. He was in love with a girl (you), but thanks to the fans, you two never ended up together.
