It could be that Natsu wants to take Lucy on a special mission without the interference of the rest of the guild. He thinks that by 'kidnapping' her, he can get her alone and they can handle the mission more efficiently, not realizing how his actions might be misconstrued.
Maybe he's misinformed. For example, he heard some false rumors about a powerful enemy targeting Lucy specifically. His protective nature towards Lucy then kicks in and he decides to 'kidnap' her to safeguard her from this perceived threat.
He could kidnap her because he believes she's in immediate danger. Natsu is very impulsive and might not have time to explain things properly, so he just takes her away to keep her safe.
Perhaps in the fanfiction's plot, Natsu makes a big mistake that endangers Lucy or her friends. Let's say he recklessly takes on a powerful enemy without a proper plan, and Lucy's friends get hurt as a result. This might cause her to hate Natsu for his irresponsible behavior.
In fanfiction, Lucy might want Natsu because of their strong bond. They've been through many adventures together. Natsu is always there to protect her, and his brave and fun - loving nature attracts Lucy.
Their wedding would be a grand affair. All the Fairy Tail members would be there. Natsu would be in his best suit, looking a bit uncomfortable but happy. Lucy would be in a beautiful white dress, with her Celestial Spirits perhaps helping with the decorations. There would be lots of food, music, and dancing. Gray might accidentally freeze something during the celebration, and Erza would keep everyone in line. It would be a day filled with laughter and joy.
In some fanfictions, if Natsu kidnapped Lucy, it could be a comical situation. Natsu might do it out of his own strange sense of protecting Lucy in an overzealous way. Maybe he thinks there's a danger that only he can keep her safe from, and his impulsive nature leads him to this 'kidnapping' which is more like a forced protection.
She would fit in very well. The Fairy Tail guild is all about family and acceptance. Given her parents are Lucy and Natsu, she'd be welcomed with open arms. She could learn from the older members like Makarov and Mirajane, and bond with the younger ones like Romeo. Her magic skills would also contribute to the guild's strength during battles or when helping the town.
Sure, there may exist such fanfictions. In the official 'Fairy Tail' story, Natsu and Lucy are very close. But fanfiction is a world of creativity and deviation from the original. A writer might decide to make Natsu hate Lucy due to some made - up reasons like a misunderstanding or a conflict of interests. This could lead to a whole new set of adventures or conflicts within the 'Fairy Tail' universe as rewritten by the fanfiction author.
Yes, there might be such fanfictions in the vast world of 'Fairy Tail' fan creations. However, these types of fanfictions can vary greatly in terms of their content and quality. Some may focus on the comical aspect of such a situation, like Natsu accidentally stumbling into Lucy's bathing area and the chaos that ensues. Others might use it as a way to develop their relationship in a more platonic or budding romantic way within the fan - created narrative.
There's a fanfic titled 'Married Life in Magnolia' which focuses on their day - to - day married life. It includes Natsu being his usual goofy self and Lucy trying to keep him in line while they both deal with the challenges of being a married couple in the Fairy Tail guild.
The guild would likely be ecstatic. Gray would probably make some snarky comment about Natsu finally growing up, but deep down he'd be happy for his friend. Erza would be all for it and might start planning the wedding immediately, giving orders to everyone in the guild to help out.
The story could focus on their journey to find a new place to belong. They might meet new allies along the way who have different values and magic abilities, which would add new elements to the story. For instance, they could encounter a group of mages who use music as their form of magic.
