Nami's message in Strong World movie
Oda drew a 'Strong World after 3 seconds' where you could clearly see Nami blushing and Luffy has a huge smile with his hand behind an ear (same as Sanji but we all know that those last few words were for). It's a really cute snippet. I'll send a link so you can see it.
