Jae Eun Kim - (16) She goes to the same school as Sey and is her best friend. She is a supporter of a Sey-Siho relationship and tries to encourage Sey to see Siho. Sey confides in her quite a lot. She makes cosplay costumes and dreams of becoming a manga artist. Jae has a crush on Simon and has put him in her manga, casting him as the main character of some pretty interesting scenarios. Those scenarios are later seen by Simon, which leads to her running away from him, believing that her chances with him are gone. They make up in vol. 5, when Simon praises her for following her heart. But it remains questionable if they will get together, since he hints to her that he is gay.
