I came here after receiving consultation from Director ㄱㅎㅅ of ㄸㅋ.
You first consult with the director about the method you want, and after consultation with the director, he shows you the lines one by one, numbering them as seen in the reviews.
It's okay to have a slit, and there's no pressure to do it if you don't want it. And when I consulted with the manager, he explained everything about the procedure and price to the point where I didn't have to ask any questions, and he was very systematic.
The location and hospital are clean and good, but I think the price is a bit high compared to other places.
