Here are examples of these “ special feelings”:
It just means that Luffy and Nami have “ special feelings” for each other whether they are aware of those feelings or not and sometimes those feelings to protect, defend, and/or support each other is more intense or displayed in a way that more than just friendship. It does not mean that Luffy and Nami favor each other out their friends because the two of them equally love and respect every single one of their friends. The bond, trust, and loyalty between Luffy and Nami is unparalleled throughout the series and every once in a while it is shown when other crew members and/or other friends are involved.
Luffy and Nami’s relationship has grown, developed, and evolved as the story of One Piece continues to progress.
