He did Sakura saw Naruto as the Annoying little brother that get in Her way. And Naruto needing attention as an orphan look to it in Sakura a lout mouth girl with pink Hair and very opinionated,what better way to get attention than to try to date Her. Remember with the exception of the Ramen Man and Daughter, 3RD Hokage,Iruka and Hinata every body else ignored Naruto’s existence. It wasn’t till the Sasuke retrieval arc that the rest of the village including Sakura started to take notice of Naruto’s worth. I want you to Imagine if you were ignored by people,you might to attract try to attract someone like Sakura to get attention even rejection is better than getting ignored.
