Jaekyung is just another University Student. A headstrong twenty one year old girl who grew up in a small town and moved to Seoul to further her studies, living on her own and making money for her expenses while staying in school.  She's poor and in debt from her tuition, she's stressed and exhausted from school and she's much too busy as a medical student to maintain a normal social life. Despite her poor family background and difficult lifestyle though Jaekyung is a dreamer. She almost died in a car accident at the age of ten, all the doctors told her parents that she would pass away. All except for one and that's all it took to make a difference. The doctor not only saved the life of Jaekyung but her parents as well. She saved them from losing their precious daughter. Jaekyung wants to be someone like that. Her outlook in life is extremely positive and her personality is bright like the sun. Even though she doesn't have a lot of time to make friends her classmates all adore her. I guess you could say her life is as normal as it could get. She's a simple girl with a set goal in mind and no intentions of ever giving up. Her typical lifestyle all comes spiralling out of control though when she meets Byun Baek Hyun, the spirit of an angry teen who was trapped from entering his body. He was in a coma. Seeing that he was lonely and afraid, Jaekyung felt sorry for him and took him in. Who knew that spirits could be so whiny?
