Naruto would probably be really excited. He loves new and cool powers, and the Sharingan is one of the most powerful and mysterious in the Naruto universe. He'd likely be full of questions and eager to see what Hana can do with it.
He might be initially shocked. Naruto is used to thinking of Hana as an ally, so if she hurts him, it would be unexpected. He could immediately try to get some distance to assess the situation and figure out why she did it.
A possible plot could be a time - travel scenario. Hana and Naruto are sent back in time to the era when the Sharingan was first created. They have to figure out how to get back to their own time while also dealing with the power struggles and conflicts of that era. Hana's Sharingan becomes a key factor in their survival, as they use it to outwit powerful enemies and make allies among the ancient clans.
Naruto might adapt by first trying to understand the basic functions of the Sharingan. He could start with the simple ability to see chakra flow more clearly. Since he has always been perceptive about people's emotions, he could use the Sharingan to read the emotions of his enemies through their chakra, which would help him in battles.
In Naruto fanfiction, the Eternal Mangekyou Sharingan (EMS) often enhances the Sharingan in several ways. For one, it gives more stable and continuous power. The regular Mangekyou Sharingan can cause blindness over time with excessive use, but the EMS doesn't have that problem. So, characters can use their Sharingan abilities like enhanced perception, predicting enemy moves, and powerful genjutsu more freely.
Yes, in some fanfictions, Naruto is given the Sharingan. Fanfiction writers often like to play with the concepts and powers in the Naruto universe, and giving Naruto the Sharingan can lead to some really interesting storylines. It might be a result of some kind of power transfer or a unique plot device.

Yes, in some fanfictions, Naruto might end up having Sasuke's Sharingan through various creative plot devices. For example, in a story where there's a powerful jutsu gone wrong that transfers Sasuke's abilities, including his Sharingan, to Naruto. This can lead to really interesting character developments as Naruto has to learn to control and use this new power.
It likely explores their relationship through shared experiences. For example, facing a common enemy or working together on a project for the village. This brings them closer as they get to know each other's strengths and weaknesses.
Their relationship could develop slowly. At first, it might be awkward as they are strangers in a way. But Naruto's friendly nature could break the ice. He might share stories about his adventures, which would intrigue Hana. Hana, in turn, could show Naruto the traditions of the Inuzuka clan. They would gradually become friends and then, as they see each other's good qualities more often, fall in love.
He could change in terms of his relationships too. His friends might be both in awe and a bit wary of this new power he has. Naruto himself might struggle with the newfound power, as it's not his natural ability. He might become more introverted as he tries to master it privately, not wanting to accidentally harm his friends with this new, potentially dangerous power.
