I keep thinking about this scenario with Sasuke x FemNaruto. Sasuke has a massive crush on Naruto, one that he's not exactly proud of. To make matters worse, he finds himself unable to actually talk to her, When the kiss happens, he throws up on top of her. Other than that though, he's not coming off like Hinata. To Naruto, he's just extremely distant and stuck up for not talking to her. So, she goes the distance to try and get him to acknowledge her. Sakura is hostile to Naruto because she recognizes Sasuke's crush, though she begins to open up more to the other girl as time goes on.
Matters are complicated after the Chunin exams, when Neiji starts to spend time with Naruto. This actually plays a role in Sasuke leaving the village, wanting to get away from it while cursing his own weakness.
