The friends from Gaara's village, like Temari and Kankuro, would be very protective. Temari would likely give Naruto the 'big sister' talk, warning him to take good care of Gaara. As for Naruto's friends, they would support him wholeheartedly. Choji might bring over some of his favorite snacks for Gaara, thinking it would be good for the baby. And Hinata would be quietly supportive, maybe knitting some baby clothes in her spare time.
The Uzumaki family, if any are still around, would be overjoyed at the news of Fem Naruto's pregnancy. They would probably start preparing traditional Uzumaki baby items and sharing family stories with Naruto. In Gaara's case, the people of the Sand Village who once feared him might now see a new side of him and start to show more support and acceptance, seeing him as a future father and a more approachable leader.
Once he realizes that Gaara is serious about the kidnapping, Naruto would start to plan his escape. He would use his ninja skills and his quick thinking. Naruto has a lot of experience in getting out of tough situations. He would look for any weaknesses in Gaara's defenses or in the place where he is being held. And while he's planning his escape, he would still be trying to reason with Gaara, hoping to resolve the situation without having to fight his friend.
Sakura might be a bit surprised at first. She has always seen Naruto as a friend, but she would quickly come to support him. She knows how much Naruto values his relationships, and if he has found love with Gaara, she would be happy for him. Kakashi would be very accepting. He has always believed in Naruto's judgment and would see this as another step in Naruto's journey to change the ninja world. Shikamaru would probably be the one to think about all the political implications but in the end, he would also support it as he trusts Naruto.
Often, a battle or a common enemy can be the catalyst for their friendship in fanfiction. Let's say there's a new, powerful foe threatening both Konoha and Suna. Naruto and Gaara are forced to fight side by side. During this time, Naruto's unwavering determination and positive attitude start to influence Gaara. Gaara, in turn, shows Naruto his own strength and loyalty. This shared experience of facing danger together makes them respect and like each other, thus forming a friendship.
A possible plot is that Gaara is having trouble controlling his inner demon again. Naruto, having experienced similar issues, offers to help him. They go on a journey to find a way to calm Gaara's inner turmoil. During this journey, they encounter various challenges and also meet old friends and foes. Through shared hardships and Naruto's constant encouragement, Gaara finally gains better control. Their friendship is strengthened through this life - changing experience.
In the fanfic, Gaara and Naruto meet by chance in the Hidden Leaf Village. Naruto is immediately intrigued by Gaara's silent and brooding nature. He tries to befriend him, inviting Gaara to eat ramen with him. At first, Gaara is hesitant, but Naruto's warm smile makes him give in. As they share a bowl of ramen, they start to talk about their dreams and fears. Gaara opens up about his lonely childhood, and Naruto shares his own experiences of being an outcast. This moment of vulnerability cements their friendship, and from then on, they are inseparable.
One common theme is redemption. Gaara was once a troubled and lonely character, and through his friendship with Naruto, he finds a path to redemption. Another theme is acceptance. They accept each other's differences, like Naruto's boisterous nature and Gaara's more reserved personality.
Naruto might be initially confused. He is used to being friendly with everyone, and this sudden possessiveness from Fem Gaara could catch him off - guard. So he may just try to talk to her to understand why she is acting this way.
One common theme is the power of friendship. Their bond helps them both grow and overcome their respective traumas. For example, Naruto's friendship gives Gaara a reason to believe in himself more.
