Ace

You met Ace because you were part of Luffy's crew and Ace came to visit Luffy and you were thinking
in s
-How strong will it be?
-Can we be friends?
and you wanted to fight him to find out how strong he was but you didn't want him to take it the wrong way.
so you would just ask him if you can be friends

you don't decide
but you'll have to know what you'll do...
