The story revolves around a young man appointed to rescue a troubled hospital who must choose between two women, a dedicated nurse or a spoiled rich girl.

Yuko is sent to the coastal regions to be raised away from the rest of her sophisticated family where she finds out from her ill grandmother that she is not who she thought she was.
