As for his love life, he could meet new people at college. There might be a smart witch from a different magical family or even a Muggle - born witch who catches his eye.

When Harry changes schools in fanfiction, his relationships take on a whole new dimension. His bond with Ron and Hermione would face a significant strain. There would be a mixture of emotions - sadness, confusion, and maybe even a bit of resentment from them. On the other hand, Harry would enter a new social arena. He might encounter students who are more competitive or more laid - back compared to Hogwarts. His relationships with them would depend on how he presents himself. If he's seen as the hero from Hogwarts, some might be intimidated. But if he's humble, he could build deep friendships. His relationship with the wizarding community as a whole would also shift. He'd be part of a different school's reputation, and this could either enhance or complicate his standing in the wider wizarding world.
If Harry was raised by the founders in fanfiction, his relationship with his enemies would also change.

If Harry Potter transfers to Ilvermorny in fanfiction, his relationships would undergo a major shift. At Hogwarts, he had Ron and Hermione, his closest friends.

His relationship with Hermione and Ron would be different. They might be a bit jealous at first of his new powers. But they would also be curious and try to help him understand his demigod side.
His personality might also be influenced by the people he meets in the alternate universe. If he meets a group of very kind and peaceful wizards, he could become more laid - back and positive. On the other hand, if he is surrounded by cruel and calculating wizards, he may become more withdrawn and calculating himself as a form of self - protection.
His relationships with his friends could become stronger. Since he's training in the Time Chamber, he might come out more confident and skilled. His friends would look up to him more. For example, Ron might be even more in awe of him, and Hermione would be proud of his progress.
