Curse Friend US

Soo-nam was sick when he was young and couldn't go to school or even get out of the house. One day she became able to see ghosts, and since then she had thought that her only friends were ghosts.  As Soo-nam got better, she could go to school and she talked to ghosts in front of her classmates without thinking about what others would think of her. In the eyes of her schoolmates, she looked creepy, so she was stigmatized as a weirdo at school. And she was bullied by Ye-ri Hong, a popular class leader at school. Soo-nam was tired of constant bullying by schoolmates on her and decided not to see ghosts any longer.
Soo-nam turns 20 this year and enters university. Her dream is to clear up the past, have normal school life, and make many friends. She attends the freshman orientation with expectations, but bumps into Ye-ri Hong, who she had always sat next to her in middle school.  And a creepy and eerie ghost inside the Ye-ri's back of the hair is seen by Soo-nam. Will Soo-nam be able to be free from ghosts?
