The rest of his friends would probably gather around him, offering support and trying to cheer him up. They'd bring him water or whatever they thought might make him feel better. They'd also share stories to distract him from the pain, like the time they had an adventure together and overcame a difficult obstacle.
Shikamaru would likely be his usual laid - back self on the outside, but secretly he'd be thinking about all the implications this has for the village and their team dynamics. He might offer some practical advice like how to manage their time and resources better now that they're going to be parents. Choji would be excited and would probably start thinking about all the delicious food he could bring for Ino during her pregnancy to make sure she and the baby are well - nourished.
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.
Sasuke often appears in different story arcs of the Boruto manga, depending on the current plot and mission. Sometimes he's on a solo mission, sometimes he's involved in events related to the village.
Naruto would be devastated. He might blame himself for not being able to protect his son. Sasuke would be angry and would likely go on a hunt for the perpetrator. His friends like Sarada and Mitsuki would be heartbroken. Sarada might vow to become stronger to prevent such a tragedy from happening again.
Sasuke would probably be very confused at first. He has spent so much time hating Itachi for what he did to the Uchiha clan. Seeing Naruto befriend Itachi would make him question his own long - held beliefs. He might initially be angry with Naruto for seemingly siding with his enemy.
Sakura's reaction would be complex. She has deep - seated feelings for Sasuke, so it would be a hard pill to swallow. However, as a medical ninja, she would also feel a sense of responsibility towards Sasuke's pregnancy. She might offer to be Sasuke's doctor throughout the pregnancy. Naruto's friends like Rock Lee would be over the moon for him. Lee would see it as Naruto achieving another great milestone in his life. He would constantly cheer them on and might even start training extra hard in case he needs to protect the new family. As for the other Konoha ninjas, they would initially be skeptical but gradually accept the situation as they see Naruto and Sasuke's determination to build a family together.
