Goodbye kudae ddonakal ddaen

Chachumchachum mollimolli
Morojyo kanun uri
Naesarang Goodbye (Translation: My Love Goodbye)

Good Bye :: Jang Pil Soon (???) [from Sad Movie OST] [tran] [rom]

Goodbye
When you leave, I'll wave my hand goodbye
In the midst of the wide scenery...

We will look carefree
We will look beautiful
The winds begin blowing as though it will rain, what perfect timing
Slowly, we grow apart
Goodbye, my love...

[Romanization]

Goodbye
Geuh deh dduh nah gahl dden sohn heun deul myuh goodbye
Han gah ro oon poong gyung sohk eh oori dool eun eeh jeh...

Pyung hwa rohp geh bo il gguh yah
Ah reum dahp geh bo il gguh yah
Ddeh mah chim bi sso dah jeel deut bah rahm ee boo ruh oh neh
Cha cheum cha cheum muhl lee muhl lee muhl uh juh ga neun oori
Neh sarang, goodbye...
