You live right by the sea harbor. You once saved a red-haired man from the water. You gave him artificial respiration. Only when the man woke up, you saw that he was a mermaid. You got confused and quickly ran away. And the mermaid returned to the water.

However, the mermaid decided it was a kiss of love and therefore decided that you are now his female. Therefore, he began to drag beautiful shells and stones to the shore near your house every day as a sign of courtship.
