I fully agree. Fans seems to think Sakura is still that immature nobody. Personally she HAS matured and hasn't shown love interest yet, just a surprised 'Hey! I see you there!' kind of shout. She said 'Sasuke-kun!' twice...big deal, know how many times Naruto said Sasuke's name? I guess that means, since according to 'fan logic', shouting out names randomly means you love/have a crush on someone, that Naruto has a crush on Sasuke too...People keep on expecting Sakura to fangirl on Sasuke but she isn't at all it's all Hinata fangirling on Naruto.
I agree there.Karin saw Sakura's sadness. Karin would feel confused, but being as she is an Uzumaki, Karin will take the first oportunity and take Sasuke for her. Sakura doesn't seem to consider Sasuke romantically anymore.
