I would like to sincerely thank you for waiting for me. It was not easy; they were times ups and downs. But to those who gave me so much strength during my service including my superiors, my fellow army music corps members, our fellow army musical cast, my family, my friends, and my beloved fans, thank you sincerely. Thanks to you, I was able to return healthy."
