What if it's between her and Tsunade? Since Sasuke's poke = his love for Sakura?
What would that make Tsunade's kiss to Naruto's forehead?
By the forehead theory:
TsunadeXNaruto should've got together.
Kabuto's hide out and find Tsunade's, Jiraiya's, Dan Kato's but Tsunade would put Naruto's DNA into the kid. So they could claim the child as their own since. They do share DNA.
