A story about love and heartbreak, sadness and self-preservation.
A naive, cheerful albeit, somewhat of a recluse writer, Han Ji Eun (Song Hye Gyo) is swindled out of everything she owns. Not by strangers, but her best friends! Stranded in China, she is determined to get home with the help of an actor, Lee Young Jae (Bi). She borrows money from him after coming up with a clever lie and plans to pay him back after landing in Korea, only to find that all which is precious to her has been sold. In an attempt to get her possessions back, she has entered in a contract marriage with Young Jae for one year. It is quite simple, until strong feelings start to develop. Everyone around them test the "love" Young Jae and Ji Eun have for one another.
In spite of it all, Ji Eun manages to be humorous and endearing - even when her heart is breaking.
