Mick is the youngest son of the Mermaid King.
As a boy, he does not have the pressure to inherit the throne like his sisters, and is very free; as the youngest, he is favored by his sisters and brothers, and has developed an innocent character. He is a silly, sweet boy who longs for love.
One day, Mick, who secretly disguised himself as a human and ran to the land, met Stephanie Windpick, the eldest son of the Earl's family. Stephanie was tall and handsome, and Mick fell in love with her at first sight and wanted to marry her.
But there are so many differences and contradictions between mermaids and humans, and neither side can live on each other's territory for a long time. Faced with these difficulties, how will Mick solve them?
