I remember back in 2012, I discovered it because of Eat Your Kimchi.
I remember just for fun trying to make some different language versions of this song. (English, Danish and Faroese)
I still really like this song, even though I find the lyrics a bit too steamy.
I still can't take the "Like a my wife girl let's have a baby" part seriously.
The song's lyrics was written by Jaejoong, and he starred in this teaser.
but there was never a drama version of the music video.
A year later another song by Baek Seung Heon got released.
He has also starred in some kdramas, like "My Lovely Girl", "Hi! School - Love On", "Something About 1%", "My Secret Romance" and "So I Married The Anti-Fan".
He also sang the OST for "Something About 1%"
I don't think he has released any new music since that one OST.
