The drama tells the story of an expert con man (played by Lee Min Ho) who stumbles upon the last mermaid on earth (played by Jun Ji Hyun) and begins living with her. However, it's obvious that their stories have been linked together throughout Lee Min Ho's past lives.

In the new set of still cuts, child actress Gal So Won will be playing Jun Ji Hyun's younger role, while actress Shin Eun Soo will be playing Jun Ji Hyun in her teen years. Child actor Jun Jin Seo is a befuddled boy in a white hanbok as Lee Min Ho's childhood role, while GOT7's Jinyoung will be portraying Lee Min Ho's teen years.�

Just how exactly are their fates intertwined? You'll have to find out when the drama premieres November 16 at 10PM KST!
