In a Luffy x Nami Lemon New World fanfiction, there could be a situation where Nami is kidnapped by a group who wants to use her knowledge of the New World and the lemons (maybe there are special lemons with unique properties there). Luffy, being the fearless captain, sets out on a solo mission to rescue her. Along the way, he meets some old friends and new allies. When he finally reaches Nami, they both realize their feelings for each other have grown even stronger during this ordeal.
In a Luffy x Nami Lemon New World fanfiction, Luffy could develop his ability to understand Nami's more complex emotions. The lemons could be a symbol of something precious to Nami, and Luffy has to respect and protect that. He might start to see Nami not just as a crewmate but also as someone he has deep feelings for. Nami could develop her sense of adventure even more. She might be initially cautious about the lemons in the New World, but as she explores more with Luffy, she becomes bolder. Their characters could also grow together as they face new enemies in the New World who are after the lemons. This would test their loyalty to each other and the crew, and they would come out stronger as individuals and as a couple (in a platonic or romantic sense depending on the direction of the fanfiction).
One possible plot could be that during a journey on the Grand Line, Nami and Luffy find themselves in a strange and beautiful island. There, they start to discover new feelings for each other. Nami might be initially hesitant due to her past experiences and her focus on the treasure, but Luffy's pure heart and his unwavering belief in their friendship gradually make her open up. And they could go through various adventures on the island together, strengthening their bond in a more romantic way.
One interesting theme could be the exploration of loyalty in a different context. In the original story, Luffy and Nami have a strong bond of loyalty as crewmates. But in a fanfic, this loyalty could transform into a more romantic and exclusive loyalty towards each other. Another theme might be the discovery of self - through their relationship. Nami could learn to trust more deeply, and Luffy could become more aware of his own emotions.
