After a month, the correction is finished. The correction I am currently doing is the second correction. I wish this correction was the last ㅠㅠ I did it when I was in elementary school and took it away from me in middle school, but even though I had a retainer, it returned to its original state and my chin became scaly, so I was very stressed. It was a correction that I started following my parents without knowing anything from a young age, but compared to the old days, the corners of the mouth that were droopy went up. My mouth is small so I sometimes chew my cheeks while eating lol
