Often, in luffy x law lemon fanfic, a theme is the power dynamics between them. Given Luffy's leadership and Law's own strength and intelligence, how they balance that in a relationship can be a focal point. Also, themes of friendship - turned - more - than - friendship are quite common, as they start from being comrades in the One Piece story and fanfics may develop it further romantically.
One common theme could be the exploration of their different personalities. Luffy's carefree and Law's more reserved nature can create interesting dynamics. Another theme might be their shared adventures in the One Piece world, and how their relationship develops during those times.
In these fanfics, a prevalent theme is the mutual understanding they develop for each other. Luffy and Law come from different backgrounds and have different goals initially. But as the story progresses in the fanfic, they start to understand each other on a deeper level. And of course, the romantic and physical relationship aspects (in the context of the lemon genre) are also a major theme, showing their intimacy and the unique bond they share.
