The First Day

It's Harry Potter and Dudley Dursley's first year of primary school. As usual, everyone likes Dudley better but Harry doesn't really mind. Join Harry as he meets more people than he's ever met before and begins to make things happen that no one understands...

Obviously this fanfic has no ships (apart from Vernon and Petunia) since Harry and Dudley are four years old, and it will be as canon compliant as possible.
