Among the artists, are there any who used jaw muscle tying instead of lip breathing? At first, I was actually only looking at liposuction, but these days, they are also doing muscle-binding surgery in collaboration. They say that this surgery is really effective, and it looks like that in the reviews, and if you had the surgery, please leave a comment. For reference, I am watching ㅁㅇ and ㅇㅇㄹㅁ.
