you are Ace's love of his life. You tried your best with the others to save him, but Ace gave his life to protect his little brother luffy from a killing blow

The next day you were still crying your eyes out. Not believing that your boyfriend, your love really died

but little did you know, Ace took the place as your guardian Angel, so he can still protect you and be there for you

Ace: please... Love don't cry okay? I know you can't see, feel, or hear me. But still, I love you! Always!
