Summary:

"Sehun’s a twenty four year old senior in college who has a lot on his hands; between balancing school, assignments, a social life and his sickly nine year old sister who is battling leukemia, life is pretty tough. Ever since his mother passed away a couple years ago, things have been going wrong. His grades are deteriorating and his little sister is hanging onto dear life when she enters the worst stage of her cancer. When there’s only one option for a cure, it’s at Myeongwoo Hospital where there is a new doctor with a new technique that never has been used before. Park Minyoung comes from a family of hematologists; she knows the disease like it’s the back of her hand. Being a child prodigy, she knows a lot about of the illness and has discovered a new way of healing. It’s a risky decision that he still makes no matter what. Little did he know, she’d be the one to heal not just his little sister but his heart too."
