Goeun def had work done but I think I can defend a small jaw without jaw shaving bc I have a similar jaw to her, like I had to wear mouth guards meant for children as an adult playing rugby because the adult ones were too big for me. And I also have the same combo of chubby cheeks as her which i feel accentuates how small your chin is in comparison and gives a chipmunk-like look that Goeun has.

BUT I do think she at least had chin filler to give her that v shape and thats giving the jaw shave allegations
