Okay this is my oponion. It's about someone who don't want to let her lover go even when she cheated and mistreated him. It's like when you sacrifice everything just to obtain their trust, loyalty and believe that they won't turn their back on you but in the end it happen the other way around. The person is still waiting for a miracle that someday his lover will return back to the way it was. In a way, it is simply a painful love story tragedy where the man still cling unto the memories with her lover and so the singer composed this story into a song as stated at the early intro before the hook of the song where the singer said that "this is my story". This is the first K-pop song I listen back in 2011 and I still listen to it every time I got the chance and it forge path for me to started to be more open with Korean-Pop Song and their Korean Culture activity.
