I decided to get a black belt and kept going to the dojo in between my singing activities, but this was more difficult than I imagined...I was having a terrible time every day. A group of 10 members who are trying to build up their bodies to regain their blanks and fight with the will to die. The instructors at the dojo I attended were very strict and did not allow me to be promoted easily, so my training became increasingly difficult. I was really inspired by how my juniors, who were stronger than me when I was still active, were able to acquire skills without me even realizing it. It was difficult to balance this with my singing career, but I knew that if I didn't work hard, I wouldn't get any results, so I always practiced hard with the mindset that I could do it. On the other hand, there were also challenges mentally. As the promotion examination approached, I found myself becoming more and more nervous. To be honest, I could only sleep for 2 hours the night before the screening. Due to lack of sleep and excessive stress, my mind and body were far from perfect, but I can't use that as an excuse. The only thing that supported him was his innate spirit. The result was...I passed with flying colors. Of course I felt happy, but my biggest accomplishment was being able to be proud of myself, knowing that I had finally achieved something that made me who I am.
