This is kind of weird question, but it just keeps bugging me and I don't know where else to ask. When watching kdramas I often notice that many actors and actresses have different mouth corners from all the other people I've seen. For example Chinese actors have "normal" mouths, but Korean actors have this deeper, different corner of mouth. I've traveled a lot in Asia (but not Korea) and never seen this in real life. Is it something that is just typical facial feature for Korean people, or is it from plastic surgery?
