Perhaps a storyline where the harem is formed gradually. Luffy starts with a small group of friends who gradually become more than just comrades. They face a common enemy that threatens the safety of the Grand Line. In the process, the harem members show their loyalty to Luffy. They also have internal conflicts among themselves sometimes about who is closer to Luffy, but in the end, they all work together for the greater good and for Luffy's dream.
One possible storyline could be Luffy and his harem going on adventures together on different islands. They face various challenges, and during their journey, they develop deeper emotional bonds with Luffy. For example, they might help him fight against powerful pirates or discover hidden treasures. Along the way, their relationships grow and there are many heartwarming and exciting moments.
Another storyline could involve Luffy's harem members each having their own unique skills and abilities. They use these to protect Luffy at times when he is in danger. Maybe one of them is a great navigator and helps them find their way through difficult seas. And as they spend more time together, there are fun interactions like cooking together on the ship, sharing stories from their past, and slowly falling in love with Luffy in different ways.
