Maybe there's a plot where Klaus is cursed, and the only way to break it is through Jeremy's unique connection to the supernatural world. As they work together to break the curse, they start to understand each other's motives and past traumas. Their relationship deepens from initial distrust to a grudging respect and eventually something more romantic as they face various challenges and enemies along the way.
Jeremy Gilbert is often portrayed as a complex character. He has a connection to the supernatural through his sister Elena. He can be brave, as he has faced many dangerous vampires.

He's manipulative, using his charm and power to get what he wants. But deep down, he has a vulnerability due to his troubled past.
Perhaps Jeremy stumbles upon Klaus by accident and Klaus initially sees Jeremy as a threat or an annoyance. But as they interact more, they find common ground.
The exploration of Jeremy's character in new situations that might not be covered in the original show. In fanfiction, a female character could introduce him to new aspects of the supernatural world or human relationships. It can add depth to his character and show different sides of him that we may not have seen before. Also, the way female characters interact with Jeremy can create new and exciting storylines.
Love against all odds is a big theme. Since they come from different worlds, with Klaus being a dangerous and often villainous character in the main show, and Jeremy being more of an underdog. Their relationship in fanfiction often defies the expectations of those around them in the fictional universes. Also, the theme of self - discovery can be present, as they both might learn more about themselves through their relationship with each other.
The 'jeremy x meets klaus fanfiction' might be centered around the clash or harmony of their two different worlds. Jeremy might come from a more ordinary background, while Klaus has his own complex and often dark world. Their meeting could be a catalyst for growth for both characters.

For instance, Jeremy might have to decide whether to trust Klaus, and Klaus might have to face his own demons in the presence of Jeremy.
Perhaps a plot where Jeremy uses his new vampire powers to protect Mystic Falls. He becomes a sort of vampire - hero. He could use his enhanced speed and strength to fight off other supernatural threats that the town faces, all while trying to come to terms with the fact that he's no longer human.
Perhaps there could be a situation where a dark magic spell in the Potter universe somehow links to the Original vampire's curse in Klaus's world. Harry and Klaus are forced to work together to break the spell/curse. Along the way, Klaus sees a bit of himself in Harry's determination and Harry realizes that Klaus isn't entirely a monster.
There's a fanfiction where Bella becomes Jeremy's mentor of sorts. This story delves into how Bella, with her knowledge of the supernatural from her own past, helps Jeremy better understand the vampires and other creatures in Mystic Falls. It's really cool as it combines elements from both universes in a unique way.
One common theme is the struggle of Jeremy dealing with the new responsibility. He might be worried about protecting the reader and the unborn child from the dangers in their world, especially if it's in the 'The Vampire Diaries' universe with all its supernatural threats.
A third plot might be Elena getting stuck in Klaus' past through some magical mishap. She has to navigate his old world, meet his family when they were still alive, and in the process, she and Klaus grow closer as they face the challenges of that time together.
