The manager, Kim, is a calculating and efficient agent for Stella. She is very composed and professional, but also cold and to-the-point. The only thing that really matters to her is how lucrative her stars are. Kim believes she knows best for her performers. She treats Stella condescendingly, and sees Stella's desire to sing her own music as just the idealistic dream of a naive child. 

While Kim is not truly malicious or evil, in her manifestation in Stella's dream, Stella's mind paints her as a cruel and evil antagonist.
