In the far away world under the sea lives a mermaid named Jeon Jungkook. He lives with his brothers Kim Taehyung and Park Jimin and his friends Kim Namjoon, Kim Seokjin and Jung Hoseok in the daylight. He is going to be the next ruler of The Jeon Kingdom.
While he's going to be the next ruler, there is a octopus named Min Yoongi. He is the next ruler of The Min Palace. Their people despise the mermaid kingdom because they made them stay in the darkness part of the sea. For Min Yoongi to be the ruler, he has to kill the King and the new ruler.
But what if he doesn't want to?
Maybe it's because he has fallen for the certain mermaid boy.

Will they fall in hell for hatred?
Will they come together in harmony?
Will they two boys ever be able to love each other?
