Seonggyeom Kim

Seonggyeom Kim is a former patient of Professor Song.

History
Seonggyeom Kim was neglected by his parents, although he does not have memories of physical abuse. He had some resentments towards his mother. Seonggyeom was treated as an outcast at school and bullied physically. He grew up to think that everyone hates him, a sign of paranoia. He developed a good relationship with Seon and wanted to live up to her expectations. Professor Chun in his notes wrote that the patient-counselor relationship was too close, but nonetheless beneficial.

Mirrors
Seeing Professor Song speak about his mental illness on television shattered his self esteem, and he wanted to know if Seon still cared about him. He started writing threatening messages and stalking her. He raided her office although he did not take anything. Seonggyeom went as far as to pose as a patient with the alias Seongjin Kim, just to see if she could recognize him. When the professor did recognize him, he dropped his weapon and was relieved.
