Did anyone thought about Sakura wearing a bathrobe when Sasuke gave her the rose and when Ino was pulling her away she was wearing the same bathrobe, what are the possibility that she saw Sasuke flirting with other girls after he gave her that rose and she got pissed about it. But Ino stops her and tells her he isn't worted.
To be honest I kind of hate that idea because it will be lame to know that the only reasong that she leg go is because he doesn't see her the way she wants.
@Slextrem your point make sence but this scene seems more like Ino pulling Sakura away, so it could also be Hinata picking on her and Ino trying to stop Sakura.
In the complete guide special there's an extended version of the rose scene in which we see Sakura getting excited and happy because Sasuke presented her with the rose. I think she even said the typical "Sasuke-kun" all happily, so in that scene she probably still doesn't know that Sasuke is a playboy.
But as I and others have mentioned before, it might be good for Sakura to notice those girls that are swooning over Sasuke since it will make her realize how immature her own feelings for him are. She will probably see herself in those fangirls and notice how childish she's acted. She'll then realize she needs to stop with that behavior because her bond with Naruto is way more important to her.
