For the teachers at Hogwarts, like Dumbledore, they might understand that Harry needs this time for himself. However, they may also keep an eye on him to ensure that he doesn't go too far into seclusion. His retreat could also have an impact on his enemies. Voldemort or his Death Eaters might see it as a sign of weakness or an opportunity to attack when he's vulnerable.
His relationship with his teachers could also be affected. Teachers like Dumbledore, who usually encourage students to participate in such events for their growth and development, might be initially concerned or try to persuade him to change his mind. This could cause some tension between them.
His potion - making skills might make him more respected by his classmates. They could come to him for help with their potions homework or for advice on how to improve their own skills.
With his close friends like Ron and Hermione, it might strengthen their bond. They could see it as a sign of Harry's humility and his desire to be more like them. Ron, who has always come from a not - so - wealthy family, might feel a closer connection to Harry. However, with some other characters like the Malfoy family, they might look down on him even more, thinking he has finally fallen from grace.
It might make his relationship with his friends a bit strained. For example, Hermione and Ron might not understand his anger at first and try to convince him that his parents were heroes. This could lead to some arguments between them.
His friends like Hermione and Ron would be deeply affected. They might feel abandoned at first. Hermione, being the logical one, would understand his reasons but still miss him terribly. Ron would probably be more vocal about his sadness and might even try to convince Harry to come back.
His relationship with the teachers might become more complex. Some teachers might respect his newfound authority over the wards, while others might be wary. For example, Snape might be suspicious of Harry's intentions.
It could strain his relationships with some pure - blood wizards who are prejudiced against goblins. They might see Harry's trust as a betrayal of wizarding traditions.
For his friends, it could be a shock. They might feel abandoned and try to find him. Hermione, for example, would probably be worried sick and start looking for clues as to where he went. Ron might be more confused and angry at first, but then realize he needs to help find Harry. His family members would be devastated. His parents (if they are alive in the fanfiction) would be heartbroken, and his siblings might feel guilty or responsible.
Some characters might be sympathetic. For instance, Padmé could be heartbroken seeing Anakin cry. She might try to comfort him, which could further develop their relationship in the fanfic. Her actions towards a crying Anakin could show her love and understanding for him.
With Hermione, she would probably be very interested in researching more about Parseltongue and how it works in Harry. She might try to find ways to help Harry control it better or understand its full potential. This could strengthen their bond as they work together on this unique aspect of Harry's magic.
