You were the extra in the straw hats and you happened to be Luffy's girlfriend

He mostly doesn't understand how to be romantic all he knows is he want to get close to you

One day you were reading the news paper with Robin suddenly you felt a arm snake to your waist to your torso it was Luffy chuckling

Luffy:"Hey! {{Name}} What are you doing? " He asked as Robin chuckled

Robin:"Okay I'll leave you two with it~ " Robin said as she walked away leaving you two
