Sakura could become very angry. She has been let down by those she trusted, and anger is a natural response. She might lash out at her friends or distance herself from them immediately. For example, she could say some harsh words to them in the heat of the moment.
Ino would be very involved. Since she's Sakura's friend, she would be constantly checking on Sakura, giving her advice on pregnancy - related things like what to eat and what not to do. And she would also be helping with preparing things for the baby, like baby clothes and a nursery.
Their friends' reactions would be quite diverse. For instance, Ino, who was once Sakura's rival, would have a mixed reaction. On one hand, she would be happy for Sakura as they have grown to be friends over the years. On the other hand, she might feel a bit envious. Choji would be excited and would look forward to all the feasts at the wedding. As for Lee, he would be over - the - moon for Naruto and Sakura. He would probably give them some long - winded and passionate speeches about love and friendship.
Kakashi, as their sensei, would be disappointed. He would hope that they could resolve their differences maturely. He might offer some advice based on his own experiences in relationships, but ultimately it would be up to Itachi and Sakura to decide whether to take it or not.
Kakashi would be more of a supportive figure. He has seen Naruto and Sakura grow up, and he would likely be happy for them. He might offer some advice to Naruto on how to handle this new relationship, especially considering the challenges they might face as ninjas. For Sakura, he could give her words of encouragement to be true to her feelings.
Sasuke might initially be a bit aloof but secretly be happy for them. He's always had a complex relationship with Naruto and Sakura, and deep down, he would see that they are good for each other.
Kakashi would be more reserved but still show his support. He might give Sasuke some advice on being a father based on his own experiences with his team. Shikamaru would be practical, thinking about how the baby will affect the village's future and offering some logical solutions to any potential problems that might come up.
The other members of their team or the village might have mixed reactions. Some might side with Sakura, understanding her point of view, while others might think she's being hasty or that they should try to preserve the relationship for the sake of the village's stability or their own friendship circle.
The rest of Team 7 and Sakura's friends in the Leaf Village would be shocked and saddened. They would all come together to figure out a way to reverse what has been done. They might seek help from Tsunade, who was Sakura's mentor, and use all the resources of the village to bring Sakura back to her normal self.
Naruto would be extremely angry and would rush to save her without a second thought. He would likely use his new jutsu and all of his strength to break into Orochimaru's lair. Sasuke, on the other hand, would be more calculated. He might gather information first and then make a strategic move. Kakashi would probably try to calm Naruto down and form a proper rescue plan, using his intelligence and experience.
