My writing used to be too amateurish, so I'm planning to revise the whole story.
After Rosinante leaves Doflamingo, he meets Sailoti.
Then he gains the treasure of his life: Felicia.
Because of the pirates' brutality, they lose their mother. After meeting Sengoku, they are adopted.
Beneath the sea's surface lies cruelty. Once Xia grows up, she wants to make the world as beautiful as she can.
The heroine is a Mary Sue. She's a Marine, but belongs to the neutral faction.
Rosinante doesn't die. Shanks regrows his arm (the mark is removed).
Multiple romantic storylines, with headcanon and out-of-character moments.
Theme: For that vast and boundless sea
