Disclaimer: I do not own One Piece. Me wishes me did, though.
Zoro was one for brute force. He never liked doing things subtly. So when he wiped up for Sanji, he never realised the cook's subtle way of hinting things.
One day he burst out, "What are you trying to tell me, asshole? Just tell me already!"
The cook smiled, and moved towards him. Zoro was unnerved, but when a pair of soft and succulent lips planted themselves on top of his, he suddenly understood. Maybe brute force wasn't the best way to do things, after all.
