I Was Transported into a Period Novel and Became a Mermaid

Full-Dive! I Rolled a Hidden Race: Mermaid!! (Not Quick Transmigration, Not Quick Transmigration!)

Two male leads!! Help me find a book 😭😭 I read it before but could never find it again. I want to read it lately, but I cannot find it. I do not really like quick transmigration.

Period Novels with Fairies

A Female Protagonist (or Male-to-Female Transformation) with a Human Torso and a Snake Tail

I don't want the female lead to be naive and innocent. Ideally, she should live for a while before turning into a mermaid. Don't make it too awkward.
