He might be angry at first. Naruto has grown up alone and had to fight for acceptance. So when his parents say they regret abandoning him, he could lash out, saying it's too late. After all, he has already faced so much without them.
I recommend "The Peasant Daughter-in-law". The female protagonist of this book also raised a child alone, while the male protagonist was the eldest young master of a peasant family. The plot also involved the situation where the female lead avoided certain people in order to protect her child. The entire novel was set in business and farming, telling the story of how the female protagonist started her own career and found true love. I hope you like my recommendation, Mwah~
The son could ask for some time and space if he feels too overwhelmed in the moment. Then, when he's ready, he can sit down with his parents and have a proper conversation. He can also share some educational resources about homosexuality with his parents to help them understand better.
In some fanfictions, Naruto may become extremely bitter. He could feel a deep sense of betrayal and this might fuel his determination to become stronger, not for the sake of the village at first, but more for self - vindication. He might isolate himself from others and struggle with his identity.
One possible reason could be that Naruto has some sort of power within him that they fear. Maybe it's a power that they don't understand and think could be dangerous, so they hate him out of fear.
Well, a common reason in fanfic could be that his parents are on a top - secret mission. This mission is so crucial and dangerous that they can't take Naruto with them. They have to sacrifice being with their son to fulfill their duties for the greater good of the ninja world.
In some fanfictions, his parents might be forced to abandon him due to a powerful enemy threatening their family. They may believe that by leaving Naruto alone, the enemy will not target him immediately, thinking he's just an ordinary orphan.
Lily would probably be very warm and welcoming. She was known for her kindness. She might immediately take a liking to Ginny, seeing her as a strong - willed and intelligent young witch, much like herself. James, on the other hand, might be a bit more boisterous in his welcome. He could be impressed by Ginny's skills in Quidditch, if that comes up in the meeting, and would likely be glad that Harry has found such a remarkable girl.
She would be devastated. Hermione is a very emotional person deep down. She might isolate herself at first, not wanting to talk to anyone, even her closest friends like Harry and Ron. She'll probably go through a phase of denial, not believing that her parents are really gone.
Aizawa is known for his strict and somewhat reserved nature. This would have a significant impact on Izuku. Izuku, who is often eager and a bit impulsive, would learn to be more patient under Aizawa's guidance. Aizawa's ability to see the potential in his students despite their flaws would also make Izuku more confident in his own abilities. He would know that his father figure believes in him, and that would encourage him to keep pushing himself. Moreover, Aizawa's dry sense of humor might also influence Izuku's own sense of humor, making him a bit more sarcastic in a light - hearted way.
