A lively and bright human girl with Qingyan suddenly encounters a family change, her boyfriend breaks up, her father commits suicide, and her mother is terminally ill. She spent all her family wealth to treat her mother, but she could only watch her mother's life pass away.
By chance, she learned that mermaid scales could cure terminal illnesses, so she had no choice but to seek help from the mermaid Lord Croesus whom she met by chance. The mermaid master had used her abilities, seen her intelligence, and ridiculed her. He had already fallen in love with her and tried his best to help her.
Qingyan and Croesus understood each other, fell in love with each other, eliminated all resistance, and decided to join hands for life. At this juncture, humans learned that mermaid scales could cure terminal illnesses and came in large numbers. The mermaid clan was in danger of being exterminated. The mermaid emperor tried his best to save the whole clan, but had no choice but to marry a princess of the same clan and give up his beloved Qingyan.
After learning that she was abandoned, Qingyan became self-reliant and did not complain. Many years later, the mermaid owner, who was now single, met Qingyan and her children playing at the beach...
"You are married and have children? Is this child mine?"
"What do you think?"
"Impossible, we are not the same species, how can we have children."
"But mermaids also go from the shore to the sea..."
