One sided

No, because imagine while they bicker like usual and maybe get carried away with the petty insults, headbutting and all. And their faces are way too close and maybe Sanji says something stupid like "if you like fighting me so much do something about it" and Zoro pulls him into a kiss. It's hardly a pull, as they were a mere inch away from it anyway. And then Sanji pushes him back with all the force he could muster up - face red and disgusted, tears streaming down. Zoro expects him to lash out in anger. And honestly it would have been better than the answer he got. Sanji couldn't even look him in the eyes as he wiped his mouth with his sleeves. "Fuck..." it was spat with the poison so visceral it made Zoro freeze. Sanji rushed to the bathroom and spent the rest of the day washing off his mouth.
