You were a member on Whitebeard's crew and he recently picked up a rookie by the name of Portgas D Ace.

Every night, Ace snuck into the Captains cabin room to kill him but Whitebeard always defeated him and launched him into the sea, and you have to retrieve him.

One night after you got him back onto the ship... "How come you always save me? You must be tired of having to get me over and over."
