Haruno Sakura has always been the crush of Naruto. Sakura was not that interested in Naruto in the beginning of the series where showed a lot of hostility to Naruto. Gradually, they both become friends and this makes Sakura care for Naruto as a friend. This relationship can end in romance, as they both are the leading characters of the series. However, Sakura is romantically involved with Sazuke, the biggest enemy of Naruto in the series. This can be the chief hindrance in Sakura being the romantic partner of Naruto.Even though, Sakura and Sazuke are not in great terms now, she still loves him and there are great chances for both to be reunited. The chances are high, as Sazuke has once called Sakura, one of his precious people and Sakura still loving him.
Hyuuga Hinata is another character in the series that has chances of ending up with Naruto. Hinata is a girl who has a crush on Naruto right from the beginning. She is a shy girl and the crush she has on Naruto is so strong that she faints whenever she goes near him. Even though she is smarter than Naruto, she has never seen him that way.
Hinata is one among the few people who admires Naruto from the beginning for his courage, strength, confidence and determination. All that takes Hinata to end up with Naruto is a little courage for her to go up to him and make the confession. Most probably, Naruto will end up with Hinata and Sakura with Sazuke.
