Mermaid Whispering

More than 300 years ago, the legendary pirate captain YEN buried a large amount of treasure in the blue sea. YEN's later generations, Dong-Jing and Bei-Wei grew up with their father. The brother's whole life was about finding the treasure hidden in the ocean, until life taught them that the real treasure was with them all along, their love for each other. The father and the sons, who used to have a great relationship, gradually change as they grow up and have serious differences about the definition of "treasure". What is the so-called "treasure" of the father? Will the sea that once linked these two brothers' feelings be able to make the East meets the North again?
