The story of this K-drama is well developed, despite being dramatic every second of it. Everybody cries and everybody fights. The bromance between the two male actors is well portrayed. They are very good actors. But the female lead... she is soulless. When she calls to her American peers you can barely listen to what she is saying (so soft spoken maybe shy to speak in English?). That voice tone is not good for the character since it was supposed she studied a medical degree in the USA...so, not good acting). The connection between the couple is not there. He is more expressive and intense, but she is like absent.
