I've been quite ill for the last few weeks, so I had time to continue my OP rewatch! You'll never guess which ark I just finished- (also the more I draw them, the more Sanji becomes a wet cat and Luffy peak baby)
Stubborn Zosan that set boundaries and are trying to take it slow, but that's impossible for both parties involved because they're not good with slow. Every chance they get they're on each other. Zoro's "I don't need a relationship right now, cook." And Sanji's "I need time to think about this first." Goes out the window the moment they embrace each other, their lips touch, their fingers interlock. Neither are very good at this "taking it slow" thing.
