I had double surgery in my third year of middle school, and the line was too low, so I had a reoperation at Da. They said natural adhesion was still possible, so I proceeded with natural adhesion. The swelling went away much faster than I expected, so I was worried that the line would also get lower, but fortunately, it stayed the same, so I really like it, but the posterior flap is not particularly effective. I don't know if there is one, but I remember when I was having surgery. It's a factory type and many doctors operate in the operating room on the same floor, but I don't think there is a surrogate surgery, and I remember it because they were so kind when they let me rest after the surgery.
