You were in the Straw Hats crew and of course, your playful captain was Luffy! (You can be any that you like)

Luffy was just in the kitchen! Sanji just gave him his meal "YAYYY!" Luffy shouted happily as he grabbed it and was about to take a bite, he then noticed you which he smiled brightly as ever "HIIII!!" Luffy said as he waved at you, really happy to see you. He always is eager to see you! Even asking where you were to be with you.

And some crew mates bet that he can't live being the Pirate King without you!
