This is not necessarily true. Sm is an entertainment company that pays great attention to appearance and strength. Most students who have persisted for a long time have not made their debut because of missing opportunities and vocal cords and other physical reasons. As for wages, I think everyone knows that Kim Jae Jung, Park Youchun and Kim Su-jun left sm because of unfair slave contracts. The contract stipulates that artists should not only explain their studies, whereabouts, friends and family, but also report their private lives. Needless to say, the salary. Sm Company is famous for its unfairness. . . This is just a personal opinion.
