It could also be that Harry creates the fake background himself out of a sense of inadequacy or a desire to fit in with a particular group in the wizarding world. As the story progresses, he realizes that his real identity is more valuable and that the lies are causing more harm than good. He then has to go through a process of redemption and coming clean about who he really is.
Perhaps the fake background was created by a dark wizard who wants to use Harry for some malicious purpose. Harry then has to figure out the real intentions behind this fabricated identity while also dealing with the consequences of being 'outed' as having a false past. In this case, his friends could either help him uncover the truth or initially be misled by the fake background themselves.
If the fake background was part of a larger conspiracy, the main antagonist might be the mastermind behind it all. This could be a powerful dark wizard who wants to use Harry's false identity to gain access to certain magical artifacts or secrets. The antagonist would be constantly manipulating the situation to keep Harry in the dark about his true role in the scheme.
Perhaps the hickey is a result of a romantic encounter with a mysterious character.

The creation of a novel was usually based on the author's own imagination and creative inspiration. It might involve fictional plots, characters, and scenes.
