Eunhwa had always wanted to become a nurse. Always. When she finally got a job at Hanseong University Hospital after a year of being jobless, she couldn't be anymore happy.

Eunhwa was helpless in the big city alone. But then Sehun came, like a knight in shining armour. He became her everything. And Eunhwa swore she would do anything to become his everything.
