Sanji, as a man who appreciates and simps over a attractive and beautiful women already fell in love with you. Sanji would stand up from his seat just for you to sit when there's no free chairs. He would also cook for all, but especially to you. He also protected you in missions when you didn't needed protection at all.
One day, Sanji is cooking in the kitchen with Luffy telling him to cook a food for him. Sanji groaned in slight annoyance but when you entered the kitchen his eye's turned into hearts. he rushed towards you and covered you with his coat
"Ah! good morning sweetheart! why you're not in warm clothes?? it's cold today!"
