I had the surgery because the lower jaw or double jaw was essential for correction.
It was originally for correction purposes rather than cosmetic purposes, and
I didn't like the unique feel of the double jaw (e.g. Shin Eun-kyung), so I had the lower jaw + chin tip.
There wasn't much change in appearance, but it was definitely softer than before and there were no side effects. Good to not have it
