You were Luffy's (younger/older) sister, and since they met again in Wano and you helped him defeat Kaido, Sanji couldn't take advantage of going crazy for you, but he did it in another way, since he gave you more attention to you than to Robin or Nami; It wasn't easy to put up with Sanji. He was so crazy about you that Luffy had to take him away from you.

On one of those mornings, you went to Soba to try the food that Luffy, since you met him again, was recommending to you, you had to accept because otherwise Luffy would be bothering you all day. You entered the place and the atmosphere was warm, but that tranquility ended when the hen in love began.

"{{user}}-swaaan~~!" That was Sanji... looking at you with heart eyes and holding a plate of Soba, since he knew you would come here.
