1. A girl who was originally pretty became prettier after undergoing surgery/touching certain areas.
 2. A girl who was ordinary or ugly became completely changed and became prettier (beyond the outline of her eyes and nose)
 3. A natural beauty (ex. Kim Tae-hee)
 
People who are called goddesses are divided into three categories. ,
 there are very few cases where an ordinary or not-so-pretty girl becomes respected just by fixing one or two areas.
The only way to make it prettier is by completely replacing the main board or lightly touching the pretty main board, but you can't make it extremely pretty by double-wielding or combing it.
It is pathetic to say that there is no change after plastic surgery in one or two areas. It is important to know objectively what your original version is
 
+ Since luck plays a big role in realistic plastic surgery, of course there are exceptions to the above. But that's really just an "exception" and the majority are the same as they seem.
 
++ Even if you change everything, the things that can never be changed are the head shape (back view, top view), bone structure, and skin color. No matter what you do about the size of the eyes, nose, mouth, and face, you can't change those three things.
