Well, clearly Lucy and Natsu are the main characters. Lucy is often depicted as a smart and resourceful character, while Natsu is more of the impulsive and strong - willed one.
One interesting plot could be that they meet in a virtual world while on a quest that is only possible online. They have to team up to defeat a digital monster.
Lucy could be an ordinary girl who stumbles upon the dragon by accident. Maybe she was just exploring an old forest or a mysterious cave when she came across it.
There could be such a fanfic out there. However, the world of fanfiction is vast and unregulated. It's possible that it exists on some niche fanfic platforms. But it's also important to note that some fanfics may deviate from the original source material in ways that some fans might not like. So, even if it exists, it might not be to everyone's taste.
They can develop their relationship by having small, everyday moments. For example, sharing breakfast together as a family, where they talk about their plans for the day. Natsu could show his love for Lucy by being more protective of her and their family in dangerous situations. Also, they could have inside jokes that only their family understands, which would strengthen their bond.
One character that would be interesting to include is Mirajane. She has a motherly and observant nature. She could be the one to nudge Natsu and Lucy in the right direction when it comes to their relationship. For instance, she might arrange for them to go on a mission together that she knows will bring them closer. Laxus could also be in the fanfiction. His powerful presence can create a sense of danger or protection. If there's an outside threat to the guild while Natsu and Lucy are exploring their relationship, Laxus could be at the forefront of defending the guild, which would impact Natsu and Lucy's situation. And don't forget about Cana. She could be the one to create some light - hearted chaos, like daring Natsu and Lucy to do something that ends up bringing them closer, such as a bet that leads to a shared adventure.
As they travel, their bond deepens. They start to rely on each other more. Natsu becomes more protective of Lucy, and Lucy begins to understand Natsu's impulsive nature better.
She might start to blush furiously. Given her character, she is a bit shy when it comes to romantic matters. And then she might start to stammer out a response, not really sure what to say at first. As she composes herself, she could tell Natsu that she has feelings for him too but in a very gentle and sincere way.
A popular one is 'Dragon's Love for the Celestial Mage'. This fanfiction takes their relationship to a new level. It starts with a simple adventure but soon unfolds into a story of deep love and loyalty. The author does a great job of portraying Natsu's dragon - like instincts when it comes to protecting Lucy, and Lucy's growing feelings for Natsu are also well - written.
Well, it depends on the specific fanfiction. There are thousands of fanfictions out there, and some might misinterpret or twist the characters' personalities. Natsu is generally seen as a passionate and sometimes hot - headed character in the original, not an abusive one. However, in certain fan - made stories that aim for a more 'dramatic' or 'dark' take, they could write him as being abusive to Lucy. But these are not in line with the general perception of the characters.
