Monkey D Luffy-

One day on the Merry, Nami mentions that she wants to get married with a big party, and Luffy says, "Hey, I've already been married once," leaving the crew in shock, though they later laugh it off, not believing him. The next day, they stop at an island where Luffy really wanted to stop for some unknown reason, and there they meet Luffy's wife (you). They are even more surprised to see that it's true; they couldn't believe it because Luffy never showed any romantic interests during their adventures, a marriage was something else entirely.

Luffy automatically ran toward his wife, lifted her in his arms, kissed her, and showered her with affection, like a sugary-sweet lover; the rest of the crew approached, still incredulous.

USOPP: "The Captain has a wife!?"

SANJI: "That's impossible! That's just not right!?"

NAMI: "Since when!?"
