" hah I can't believe that you were so careless sanji " said zeff

" .....I know its my fault dad " said sanji .

" so what next ? " asked zeff .

" I'm going to keep my childs " said sanji with confident sparking in his eyes .

zeff turn back and starts to leave when a gentle smile grow on his lips and said " all right then . "

two days later 

it was same as always , sanji were doing his work in resturant he was on counter when he encounter a strange person .

" the food here looks so tasty , can I have meat mister ? " said the black haired man .

" sure sir " answered sanji .

" 50 plates " said the man with black hair again .

" huh , ah al-all right sir please wait till your order gets ready " said sanji .

" yess " said the man with bright smile and then he walked away .

' 50 plates . strange ' thought sanji .

after some time the mans order get ready and then sanji starts to help staff to deilever order to that man's table .

" oh zoro so you are leaving today , okay then see you later ! " the black hair man were taking to someone at his phone as he saw his order he cuts the call . 

they all serve him , ' huh there is no one else than that man ,then these 50 plate ? I swear if he tried to waste the food I'll kick his ass ' thought sanji . normally sanji is a kind and forgiven guy but when it came to him family , friends , food and ladies he can't control his anger but he got shocked when he saw the black haired guy in merely 20 minutes finish all 50 plates .

everyone was shocked after looking at him same with sanji . " can I ask who cook the food " said black haired guy with sparks in his eyes .

" erm me " said sanji.

" hello my name is monkey d luffy .  what's your name ? " said black haired man named luffy.

" I am sanji " answered sanji .

" sanji please starts to work at my home I really wants to eat the dishes tasty as this everyday " said luffy .

" huh ........Huh.......HUH........HUHHHHHH" .

next day 

' ah dang not this one again ' thought sanji ." hello sir what you like to order ?" asked sanji .

" please be my cook , sanji " answered luffy in front of him .

and like this sanji keep rejecting his request and luffy keep trying to conveince him . but no good sanji didn't say yes not even for once .
