When I was high school student, I was so nervous and depressed. Because the SAT is near at hand, I was sensitive. Around that time, I got a bad score in some exams, I thought there is no good way except to give up SAT. All of sudden, my friend suggested me this song, HERO, for me during lunch time in school. Beautiful notes, lyrics and voice made me moved. Especially, the lyrics gave power to me almost being dead on my feet. Thus, I listened to this song everyday, every break time. ' You don't be afraid, don't worry.' It has given hope and courage for people who exhausted.
