Sort of hilariously, Naruto has better chances here-- Sakura lacks any of her Naruto-was-such-a-pain memories that made her not like him when they were young, and she likewise lacks any of the we've-been-on-a-team-forever family-like memories of him either. All she knows is he's friendly and fairly attractive and that's pretty nice!

I'm not sure how things will go with Sasuke, honestly; it will depend on how he treats her now, more than anything. Since being hopelessly in love with someone and just remembering that you are/were are two really different things.

Sakura is currently all about Learning Things to be Useful -- does Jaina have anything particular teachable skills?
