How do you marry nami in two days?

Answer 1

It is impossible to get any of the girls to marry you in two days. One being that you don't get the feather until a little on later in the game. However, to get Nami to like you enough to the point where you could marry her, you should give her milk and items from the dig site everyday. She is the hardest to marry, because she won't take simple things like flowers, like the other girls will.
