The protagonist wanders and grows up alone in the front, and will stay in the Straw Hat Pirates for a while to help Luffy grow up. But he will not join the Straw Hat Pirates. The protagonist's self-experience has ended, and now begins the life of the Straw Hat Pirates. (PS: This is a story about dreams, about youth, and also a novel that makes up for regrets) (PS2.0: Ask if anyone has read it π_π, can you leave more comments, even criticisms...
