Huan Yue is a human who transmigrates into a book as its tragic heroine: a beautiful mermaid who dies for love.
On her first day in the book, she faces a fishy choice: return to the sea and avoid every human in the story, or live a different kind of fish life on land.
Sitting on the beach, Huan Yue sighs for the 103rd time before finally deciding to become a salted-fish queen.
...Well, she can't swim, and she's afraid of water.
The male lead's "pursuit" grows more and more relentless, and Huan Yue grows more and more cowardly in her efforts to stay alive. So, on a dark and windy night, she sneaks into Prince Teng's estate. Huan Yue clings to Prince Teng and weeps bitterly, scattering luminous night pearls across the floor. "Your Highness, please take care of this fish!"
Later, Huan Yue achieves her dream and gets fat and healthy under his care.
The curtains close on every side as red candles flicker. Prince Teng licks his lips in satisfaction. "Raise a fish for a thousand days, eat fish for a lifetime. What a bargain!"
Everyday life.
A true mermaid who dreams of becoming a salted-fish queen x a rough-and-ready prince whose first priority is raising fish (his wife)
