I went to the Gangnam ㅇㅅ dentist. He was the director. I went there because I had been stressed out about my long face and chin since I was young. He was kind and explained everything thoroughly and showed me before and after photos of similar cases. The conclusion was that I could do it, but the amount of change was minimal. However, because the chin is protruding, it is possible to create a confident face and impression. He said this. But the cost is also expensive... I have to go through a year of post-education training, so I felt disappointed and wondered if it was right for me to do it.
