Well, it could start with small gestures. For example, Luffy might share his food with Boa Hancock, which is a big deal for him. This simple act could make Boa Hancock see his kindness in a new way. Then, as they interact more, they might have some accidental physical contact like brushing hands. These little things can build up the tension and start to develop their relationship.
Well, a very common theme is the power dynamic. Hancock is a powerful pirate queen and Luffy is also a very strong pirate.
