Singer Ok Joo Hyun expressed her sadness about Lee Hyori getting married through a song.

Today, Ok Joo Hyun posted on her Twitter, "Ruby, To leader Hyori" along with a video.

In the video, Ok Joo Hyun played the piano and sang the song "Ruby."

One of Fin.K.L's big songs, "Ruby," says "Fine I will let you go. I don't expect anything from you, my desire is to keep you with me forever."

After singing those lines, Ok Joo Hyun yelled "Leave" at the camera, arousing laughter.

Lee Hyori had clarified all rumors and confusions by writing on her fan website on July 4, "To get straight to the point, we are getting married. We did say September would be a good time but we haven't even talked to our parents about it yet so nothing is set in stone."
