Sanji: "Luffy, what kind of me would you prefer? The old me who is useless when the enemy is a woman... Or a cold-blooded “Science Warrior” who can hurt anyone as you wish!! Which one would be more useful for the “Pirate King”...? "
I am pretty sure Luffy loves Sanji just the way he is but it would be nice to see him drop the chivalry when the lives of his mates are in danger. This is why I like Luffy, hands rated E for everybody.
