[One Piece] How Can I Find a Way to Survive After Being Reborn as a Mermaid?

As a miserable office worker,

I'm either working overtime or on my way to work overtime every day.

But one day, after working late and going home to sleep,

I suddenly discovered that I'd been reincarnated in another world and turned into a deep-sea mermaid (?).

At first, I thought I'd landed a cameo in the Little Mermaid show at the Disney next door,

but it turned out I'd arrived in the perilous world of One Piece.

Is this all an accidental journey to another world, or a fated arrangement?

Note: There are hidden details. This isn't an ordinary mermaid.

A friendly reminder: First-person narration, with a pairing.
