We'll never be apart, you say. 

I've given you everything but that was never enough.

I guess I was wrong about you. Maybe this is the punishment you deserve.

The only word that people will say when asked to describe Chaerin is 'Lucky'. 

Chaerin is lucky to have a rich dad who is a chief of surgery in a prestigious hospital in New York. 

She has a caring and lovely elder sister who has a husband and a daughter. They're also well off.

Although her mom already left this world before she can see Chaerin succeed in life just like her sister, Chaerin has someone she can be proud of.

Chaerin has this smart and humble doctor girlfriend called Dara to whom she always considers a hero because she saves a lot of people's life including hers. 

Chaerin is lucky, she got almost everything. But a person will never be satisfied of what they have right now.

Human are greedy.

And now Chaerin's life is tested.
