She was pretty. He would at least give her that. But he would never actually say it to her face. She had those eyes that shown like emeralds. That was probably only because of the tears. He wished she wouldn't cry it just made her more annoying. Her hair was probably most eye-caching feature. That was only because its cotton candy pink he told himself. Somehow even though it was the strangest color it complimented her features. She wanted him to stay and he might stay for her beauty. But he had to avenge them.
She probably really did love him. He couldn't remember what it was like to be loved. She clearly went out of her way to stop him from leaving. She could help with his other goal. The sight of a little Uchiha boy running around with bright pink hair flashed through his mined. He new if he stayed here he would eventually fall in love with her too and that little boy would maybe one day exist. He couldn't though he had to kill his brother.
She probably could make him happy. He never could bring himself to be happy after his family was killed. He always thought that he couldn't be happy because they weren't alive. Being happy didn't help him get stronger. He needed to be stronger. Being happy was unnecessary. But just because it was unnecessary didn't mean he didn't want it. He'd be happy when he avenged them.
She probably would scream. He couldn't let her stop him. He simply jumped behind her and knocked her out. He hoped she heard him say thank you. He thanked her for a simple reason. She was his friend, probably the only person who cared for him and the only person who made him want to stay. He couldn't stay though; he had to meet Orochimaru
