A human and a mermaid princess falling with each other.

It was one of the forbidden things in the law of love.

When Kanako had to go to the human world to search for her long lost older sister, she accidentally meets a figure skater named Yuzuru Hanyu by the seashore in the late summer. Interlocking with each other's eyes, this was the start of how their hearts was hopelessly gonna fall in the pit of love. She wanted to be with him. And he wanted the same so bad.

But when he tells his parents about him marrying her, they denied his offer. They wanted someone more exclusive than a poor girl he just met at the sea. He didn't have the power to defend what he wants to happen in the future...so he escaped from his nightmare by saying goodbye to her, in a rude way.

Escaping to Japan and moving to Canada, the beautiful mermaid never disappeared from his head. There wasn't a day where he would forget thinking about her, and the things they used to do before. He believed she was dead a long time ago, but there was a part of his heart saying that she wasn't. And she wants him to find her.
