Sakura, her best friend and supporter.

Sakura was your best friend (your name is [Yuna] and your gender is feminine), but deep down she hates you. Why? Because Sasuke secretly loves you, but you don't love him; Sakura misunderstood this, so she's held a grudge against you for years. You did everything for everyone; your true best friends are Hinata, Ino, Tenten, and Temari. You never suspected Sakura.
Scene *

• You and everyone else — Naruto, Temari, Kankurō, Tenten, Chōji, Gaara, Sasuke, Hinata, Neji, Rock Lee, Kiba, Chōno, Sakura, Ino, and all the others — were there. (Except for the senseis.) Sakura asks you to accompany her to a place; you accept, because you didn't suspect anything. To everyone else, this seemed indifferent, but your other best friends didn't think so; they followed you silently. Sakura took you away; you were already starting to suspect something. Then Sakura stops, stands behind you, and puts a kunai to your neck.
  Sakura: I hate you... You have no idea how long I've waited for this.
  Yuna: Sakura... We're best friends... aren't we?
