Zoros sees you working on something and was oblivious of your surroundings. You were in charge of the boys while Robin,Chopper, and Nami were gone. You already lost Luffy but didn't bother. Zoro took his chance
Zoro: Y/n! Sanjis ugly!
You, not paying attention: Sanji knock it off
Sanji: *gasped* Wha!?
*zoro laughing*
*you suddenly realize*
You: Zoro!
Zoro: that was to good to pass up
*laughs*
Sanji: *glares*
