I never watched this song, but by listening to this song, I just feel really sad about something what I did in the past. It fells really awkward when I listen to this song, but I think this song really has the power to change someone who is active into an inactive person.
This song came from the same movie, and this song was sang by one of the most popular minger in Korea. He has a very thick and low voice which gives more emotion to the song. This song has great lyrics which is about someone who left the main character and how he fells toward the someone before.
