In the world of fanfiction, the reactions can be really creative. For example, Tsunade could see this as a sign of Naruto growing up and becoming more responsible, so she might offer some special privileges or rewards. Kakashi, being Naruto's former teacher, would probably give Naruto some advice on marriage and how to make it work. And the villagers, in general, might be quite surprised as Naruto is a very important figure in the village, and his marriage to Ino would be big news. Some might be happy, thinking it would strengthen the bonds within the village, while others might be gossiping about how this relationship came to be.
The other characters' reactions would vary. Hinata could be happy for Naruto, even if it's not her he's proposing to. She has always respected Naruto's choices. Kiba might make some teasing remarks, like joking about how Naruto finally settled on Ino instead of chasing after Sakura all the time. And Choji would likely be supportive, since he's friends with both Ino and Naruto. He might offer to help with the wedding preparations if things go that far.
The other guild members would also have positive reactions. They would see it as a celebration of love within the guild. There might be a big party thrown in their honor, with everyone bringing gifts and sharing stories. Some of the younger members might look up to Natsu and Yukino even more, seeing them as a perfect couple and an example of true love.
They could start as friends who gradually realize they have deeper feelings. Maybe they work together on a mission and see each other in a new light. Naruto could notice Ino's intelligence and kindness, and Ino could see Naruto's growth and determination.
Well, one possible plot could be that after years of fighting side by side and having a deep understanding of each other, Sasuke finally realizes his true feelings for Naruto are more than just friendship. He might plan a very private and special moment to pop the question. Naruto, being the open - hearted person he is, would be initially shocked but then consider it seriously as he also values Sasuke deeply.
Sakura would probably be very surprised and might feel a bit of jealousy if she has some lingering feelings for Naruto. She could act cold towards Ino or Naruto for a while. Shikamaru, being Ino's friend, might tease her about it a lot, but also be a bit protective. Choji would likely be more concerned about how Ino feels and might offer her some snacks to cheer her up if she's flustered.
If he asks Hinata, she would probably be overjoyed. She has always been in love with Naruto, so her answer would most likely be an immediate 'yes' with tears of happiness in her eyes.
Sakura might be worried about Naruto. She could try to comfort him and encourage him not to give up. She might also be angry at Jiraiya for abandoning Naruto, seeing how much Naruto has been through already. Kakashi, on the other hand, would probably step in more as a mentor. He has his own way of teaching, and he'd want to make sure Naruto doesn't go astray.
Well, in this fanfiction, Naruto could be nervous as he asks Hinata to marry him. He might fumble with his words a bit at first. But once he gets going, he would talk about their journey together, from being classmates to comrades in battle. Hinata, on the other hand, would be in shock initially, but then her love for Naruto would shine through and she'd accept with tears of happiness in her eyes.
Sasuke might be a bit taken aback at first. He has his own complex relationship with Naruto, and seeing him look like Minato could add another layer to it. He might feel a strange sense of déjà vu. Kakashi, on the other hand, would probably be filled with a mix of emotions. He'd see Minato in Naruto and might be more protective or have higher expectations.
Sakura might be really shocked. She always saw Naruto as a friend and a fellow ninja, and this would be a completely unexpected development. She might be a bit confused about how this would change their relationships. Sasuke, on the other hand, might be more indifferent on the surface but secretly curious. Kakashi would probably be very concerned. He's always been like a mentor to Naruto, and this situation would raise a lot of questions for him about Naruto's future and how this would affect the village. And the elders of the village would likely be in an uproar. They are always worried about the stability of the village, and this would be a huge bombshell that could disrupt the village's order.
One possible plot could be that Harry plans a very elaborate and private proposal. He takes Ginny to their favorite place in Hogwarts, perhaps the Room of Requirement set up as a beautiful garden filled with the flowers Ginny loves. He gets down on one knee and tells her how she has been his rock through all the post - war chaos and how he can't imagine a future without her.
