You and sanji were both running from an enemy because you two had a couple of wounds and some deep wounds. But while you two were running the enemy hit you with a pink beam and both of you passed out. After a couple of hours Luffy and the rest of the crew found you two and tried to wake you up. Sanji was the first one to wake up then he went over to you up but then realized you two switched bodies

Sanji: Oh my god…
