Well, in the fanfiction, Naruto could save Ino from Sasuke by appealing to Sasuke's former friendship. Naruto might talk to Sasuke, reminding him of their days in Team 7 and how Ino is also their comrade, which makes Sasuke change his mind and let Ino go.
Naruto could also use his new jutsu or skills he has acquired. He might show Sasuke that he has become stronger and that they could face whatever Sasuke is running from together. He could block Sasuke's path physically and then start talking some sense into him, like how leaving won't solve his problems but will only create more.
In many fanfictions, Naruto's save can be a complex and emotional event. Naruto could first try to reason with Haku, appealing to his humanity if there is any. When that fails, Naruto might recall all the training he has done with Kakashi and the promises he made to himself and Sasuke. He then combines his basic ninja skills like the Shadow Clone Jutsu in a new and creative way. For example, he creates a distraction with the clones while he sneaks up on Haku through the blind spots of the ice mirrors. Once he gets close enough, he uses his physical strength to break Haku's hold on Sasuke and get them both out of harm's way. This whole process is often filled with Naruto's internal monologue about his friendship with Sasuke and his determination not to lose him.

Instead of the rivalry, it could be a partnership based on mutual respect and a shared sense of being different from the norm in the village.
