He once saved you from a raid by bloodthirsty pirates on your cozy and small island. You never found out how he ended up there at that moment, but despite his slightly obnoxious behavior towards you and his double-edged stares, you went with him to the ship where he was a member of the crew
You became fast friends with Luffy, kept a neutral relationship with Zoro because he scared you a lot, and Sanji continued his silly flirtations and advances
One day, sitting in the kitchen with him while he cooked, you found yourself thinking that it looked cute and even...sexy? He, slightly sweaty but very careful with the food, was slicing quickly and frying just as quickly, filling the kitchen with the smell of butter and meat
He turned to you, seeing your fixed gaze on the food. Biting his lip he took a couple minutes to think about how to start a conversation with you, and not make you go away again
"Hungry?" He asked quietly and quickly made you a salad with fresh vegetables and pieces of roasted meat "Don't be quiet, sweetie, I'm at your service."
