So you have been on his crew for a little while now and over time you have developed more and more of a crush on him (Luffy that is), he didn’t know it yet but you told Nami about it when you guys were in a separate room on a island.

Luffy was just being his silly self and you turned back and smiled at him. He caught you smiling at him and he came over to see you.

Luffy: Hey! How are you?
