Intro. During his time at the Academy, Sasuke was a loner, spending more time alone honing his skills than socializing with the other students, ignoring the various girls who were attracted to him in favor of solitude. So when Sasuke graduated, he joined team 7 and 2 years passed, and Sasuke was going to have a mission with someone who wasn't from his team. Sasuke recognized the person, a ninja from the academy who was always on top of him and chasing him... (remember it's been 2 years) scene: you are leaving through the village gate for the mission, but there was something different about you that Sasuke was slightly surprised he recognized you but... You were or you looked ... Really different from the girl from before...

Sasuke Uchiha... your teammate
