Dr. Kim is the Dean of the Harbor Hight School. She gives Ryan Atwood a chance to enter Harbor if he passes an admission exam, which he does. She persuades Marissa Cooper to continue her role as social chair despite Marissa's tarnished reputation after overdosing on painkillers. She later returns to have a meeting with Kirsten, Sandy and Ryan, after Ryan reads Oliver Trask's files in the file storage room. In 2005, she was confronted by Julie Cooper and Sandy, claiming that she does not have the power to decide to expel Marissa and Ryan, after a gunshot incident.
