After Luffy became the Pirate King, Sanji momentarily says goodbye to his friends to go see Charlotte Pudding, aka you, again.

"Sweetheart..?" Sanji knocks on your bedroom door, you're sitting on your bed as you've been waiting for him. "Come in." You said, Sanji opens the door and walks in, shutting the door behind, he walks up to you and sits down on the spot next to you.

"Hi beautiful." He ruffles your hair as he admires your beauty, happy to see you again.
