I have a friend who is an intern in Korea, so I know something about it. Plastic surgery was decided after observing you 360 degrees during the audition before debut. Seeing where your face has shortcomings will make you partially complete, and if it looks ordinary, it will be complete. Plastic surgery is decided by the company. It is mandatory to some extent. YG company requires a looser appearance and pays more attention to music. If you look alike, it won't make you complete, and you may get an injection. The remaining small shortcomings can be made up by makeup. However, YG takes a long time to practice, at least two or three years. JYP is also very good. Everything depends on the actual situation. As can be seen from their artists, there are beautiful and ordinary ones. SM pays more attention to appearance, and almost all artists have slightly trimmed it. However, the internship time of SM Company is uncertain. If you are lucky, you may debut in less than a year. Recommend more companies. Rubik's cube company and starship company are both good, you can consider giving it a try, but after all, you don't need SM YG JYP. If you debut, you will definitely have better publicity and packaging strength than those three companies, but strength is still the most important. I hope I can help you.
