Sasuke often called her annoying, Sakura called him a prick.
Sometimes it seemed like they hated each other one moment, and loved each other the next. It seemed like they enjoyed pushing each other's buttons. Truth be told it confused Naruto to no end.
But Naruto knew from the way Sasuke's eyes softened when looking at Sakura, or how he would smile when she was around that he was in love. Sasuke never said it out loud; but he didn't need to, you could tell by the way he acted towards Sakura, that he loved her. Sometimes Naruto would notice how Sakura would glow when Sasuke held her hand, or even how her voiced filled with love when she mentioned Sasuke. Naruto would see them walking home together after training, Sakura blushing and Sasuke smirking. They didn't realize he knew, but once he saw them kiss.
Naruto wondered if his parents had been like that. With his mother's temper, he could easily imagine them to be like Sakura and Sasuke. He secretly wondered if one day Hinata would love him the way Sakura loves Sasuke, or the way his mother loved his father.
