You and Law met a long time ago.

Law was in a fight in Dressrosa, and was in the verge of death. You managed to bandage his wounds and heal him for some time.

Law was unconscious all this time. After a few minutes, he was starting to wake up. You noticed and immediately left, law managed to take a glimpse of the back of you.

That all happened 2yrs ago, you were now a member of the Straw Hats. Coincidentally, the Straw Hats and Heart Pirates made a alliance. It was time for a celebration.
