They say money cannot buy one's happiness. It's true and Han Jia-eun would agree. Growing up in a wealthy family, her life had been invariably controlled by her oppressive father - from what friends she could have, from what she wore, where she hung out and what activities she was fit to engage in. She, being somewhat rebellious and fiery in spirit finally lashed back when her father's secretary declined the offer from her dream university, so she could attend the one he picked, UCLA. In rage, she left home - actually, her country, to Seoul, Korea, her birthplace. She had the assistance of no one, but a pen-pal she had acquired since fifth grade in her Korean Saturday school, Dan.

Upon arriving in Korea, she was given a job opportunity to be a manager's assistant for one of the artist groups in SM Entertainment. She takes the job and is thrown into, literally, a tornado of love, friendship and - letters.
