The theme of growth is often present. Both James and Lily grow as individuals and as a couple in many fanfictions. They learn from their experiences, become more empathetic, and this growth is what cements their relationship in these stories.
In many fanfictions about them, the theme of sacrifice is present. Given the dangerous wizarding world they live in, they might have to sacrifice personal desires or safety for each other. Also, the theme of family is important. Since they end up having a family together, stories often explore how their relationship sets the foundation for the Potter family, and how their love influences their future children, like Harry.
I really like 'James and Lily: A Love Story'. It delves deep into their relationship, starting from their initial dislike for each other to their deep, abiding love. It also includes some really interesting side plots involving their friends like Sirius and Remus. And 'Potter's Love' is also a great read. It shows how their love survived the challenges of the wizarding world around them.
A great fanfiction could be about their courtship. James could write her love letters filled with his thoughts and feelings. Lily would keep these letters hidden away, reading them when she was alone and slowly falling more in love with him through his written words.
One possible fanfiction could be about how James Potter first fell in love with Lily Evans. Maybe it started in the Hogwarts corridors. He saw her kindness as she helped a first - year student find their way. This simple act made James look at her in a new light. From then on, he tried to be less of a show - off around her.
One common theme is the transformation of James. He starts as a bit of a bully but then changes to be a better person for Lily. Another theme is the friendship group. Their friends, like the Marauders, play important roles in their relationship. For example, Sirius might encourage James to pursue Lily or Remus gives advice on how to understand her better.
One common theme is the transformation of James. He often starts as a bit of a prankster and has to grow and change to win Lily's heart. Another theme is the power of love against the backdrop of the wizarding world's chaos. Their love story is often set during the times of Voldemort's rise.
One possible plot could be about the elaborate preparations for the wedding. It might include details like choosing the venue, which could be a magical place like Hogwarts' grounds. Friends like Sirius and Remus could be involved in pranks during the pre - wedding jitters. And Lily might be having a hard time choosing her wedding dress, with her friends helping her out.
James Potter was a bundle of nerves as he waited for Lily Evans outside the Three Broomsticks. He had combed his hair a dozen times and made sure his robes were spotless. When Lily finally arrived, her red hair seemed to shine even in the dim light of the pub. They started with a butterbeer each, and James stammered out a joke that made Lily laugh. As they talked, James found himself more and more drawn to her intelligence and kind heart. They ended the date by taking a stroll under the starry sky, and James knew this was just the beginning of something wonderful.
Petunia could be an important character. She might be grudgingly attending the wedding, still having mixed feelings about Lily's magical world. Her presence could add some tension as she struggles to fit in. And then there's Dumbledore. He could make an appearance and give some wise words of advice to the couple, perhaps about the future challenges they might face together.
