Some fanfictions explore Teddy Lupin's time at Hogwarts in a more emotional way. He could struggle with feeling different because of his werewolf heritage. Harry, having faced his own share of hardships, could be there to support him. These stories often show how Teddy grows as a wizard and a person, with Harry being an important influence in his life.
Well, perhaps in the fanfiction, Harry adopts Teddy Lupin right after the Battle of Hogwarts. Teddy is just a baby then. Harry, who has lost so many people, sees Teddy as a new beginning.

But Harry, with the help of his friends like Hermione and Ron, overcomes these difficulties and Teddy grows up to be a strong and kind wizard.

Teddy might start to show some interesting magical abilities that would be quite a novelty in Forks. Harry would have to be careful not to expose magic too much, while still teaching Teddy about his heritage. And he would probably make some new friends in Forks who would be intrigued by his different ways.
He probably uses his magic in a discreet way. For example, he could use a charm to make Teddy's toys more interesting. And he would rely on his own experiences of growing up without parents to give Teddy a loving and stable environment.
Well, it could be about Harry Potter, in his younger days, stumbling upon a teen Teddy. Maybe they team up to face some sort of magical mystery in Hogwarts. For example, they might find a strange enchanted object that's causing chaos in the school and they have to figure out how to stop it.
