Its same a mermaid story , Its too very same to swing to sky and its called "swimming " in the recommandation

This drama has so many versions like once in 1998 and 2008and too in 2011 . So all the movies are same

THE fl is a mermaid and swims in the water and same in Swing to sky as she too swims. omance and comedy

There's a mermaid in the sea and then she's like a cute one , but it's not a melodrama but its a mermaid story,

It's similar again because the Fl's a mermaid and she is crazy and there is romance and comedy . Tags are same Xd Nope

It's Similar because In Legend of the blue sea , Jun Ji Hyun is a mermaid and In Swing to sky Hu Bing Qing is a mermaid . They two know nothing as a mermaid in the drama . And Swing to Sky is whole same to legend of the blue sea.
