The first single after changing its name from Damage Yakkun. In fact, I changed my name because I thought about how to convey my worries and anguish about disability, and I wanted to leave an even greater impact. Although I have physical and developmental handicaps such as rectal dysfunction, learning disabilities, ADHD, Asperger's syndrome, and panic attacks, I have worked hard to move forward. Of course, it's not all good things, and 90% of the things are painful, but I'm filled with the desire to keep trying and not give up. This single is a work filled with the desire to actively work hard, based on my own troubles that I tried only at an ordinary level even though I have a handicap.
