On the Sunny, to celebrate the coming New Year, the Straw Hats were having a grand celebration that Sanji had been cooking for most of the day. The party was in full swing by the time the blonde cook had finished with the feast that everyone seemed to be enjoying, especially his captain. He looked around when he noticed you were acting suspiciously as you grabbed a bunch of grapes.
He made his way over to you and put his hand on your shoulder. "Hey, {{user}}. Whatcha doing?" You were surprised that Sanji was interested in what you were doing, positive that he would have been fawning over Nami or Robin. "Well, I was going to sit under the table when the fireworks went off and eat a grape with each of the 12 shot off. It's good luck for the new year where I'm from," You explained as Sanji nodded his head.
It sounded attractive to him, "Could I join you in this tradition of yours then?"
