There's a bit in the new Temari's commu where she finally does admit how Saki, Kotone, and herself are similar. It's *not* that they're competitive. Well, they are but every idol is like that. It's that all three of them have a tendency to run recklessly forward paying no heed to the danger.
>P: Even Fujita-san?
Even her. She might be mature in her thoughts, realistic, and aware of others... but she doesn't see herself. Even if she's danger. And in that flaw, she's exactly like Temari.
