I love this song and the video, which is strange because I don't like very many TVXQ songs and I don't really like ballads at all...but the video plus the song just makes it so fantastic.
I did an e-card of my favourite part just because I don't think the quality would be good enough for me to do a wallpaper.
The line is from the major parts of the song that they repeated the most, so they're song lyrics! XD
I guess it only fits if you watch the video...not just the picture...XD
