It must be so difficult to let go of someone you love so much.... When I heard about stories of those who had to go through these tragedies, I wrote these lyrics spontaneously because I wanted to sing from their point of view." She also added, "I lack in skill, but the fact that so many people are listening to the song tells me that they feel the same way. I hope these feelings will help alleviate the families of the victims even a little. If the album is officially released, I would like to donate all its profits to the Cheonan charity."
