A plot could involve Edward's family finally fully accepting Vivian. There could be a big family event, like a wedding anniversary of Edward's parents. Vivian is initially nervous but with Edward's support, she wins over his family with her charm and kindness, and they have a great time together at the event.
With modern technology, Vivian could take online courses to learn about business and finance to be more involved in Edward's world. They could also use social media to share their relationship with the public, but at the same time, face the challenges of public scrutiny. Through all this, their relationship would grow and adapt to the modern - day environment.
Another plot could involve Edward making new friends in the town. These friends could be outcasts like him, and together they form a sort of club. They could then work on projects to beautify the outskirts of the town that have been neglected.
One common plot idea is exploring his past more in - depth, like his time at the military academy. It could show his relationships with other students and how he developed his skills and personality.
One idea could be exploring Edward Mordrake's backstory more in - depth. Maybe his life before the whole 'two - faced' situation, his family, and what led him to become the tragic figure he is. Another could be a modern - day encounter with someone who has a special ability to communicate with him.
One idea could be that Edward, as a cop, is assigned to protect a key witness. During this time, he discovers a complex web of secrets and has to fight against both the criminals who want to silence the witness and some corrupt colleagues. Another plot could be Edward investigating a series of mysterious murders in the city where all the evidence points to a supernatural force. He has to overcome his disbelief in the supernatural to solve the case. And also, Edward could be a rookie cop who gets involved in a big drug - bust operation and has to prove himself to his more experienced partners.
One idea could be that Harry and Edward meet in a magical forest that exists between the wizarding world and the vampire realm. They initially mistrust each other but then find out they have a common enemy and have to team up to defeat it.
One idea could be exploring a different backstory for one of the main characters. For example, what if Aria had a secret relationship with someone before she moved back to Rosewood. This could add a whole new layer of mystery and drama to the story.
A friendship - centered fanfiction could be great. Maybe a new character enters the scene and forms an unlikely but strong bond with one of the main characters. They help each other through tough times, like dealing with the pressures of the mystery and the social drama in the Pretty Little Things world.
Love is a very common theme. It often shows how Vivian and Edward fall in love or the challenges their love faces. Another theme could be adventure, where they go on quests together.
One idea could be that they go to a secluded beach and discover a hidden cove with magical properties. Another could be a trip to a foreign city where they encounter a vampire from an ancient lineage. And they might also go on a mountain vacation and face some dangerous supernatural creatures there.
