No matter how strong a person may be on the outside, everyone will have something that they rely on to let their feelings out or to express their deepest and innermost thoughts. Let alone a loner with no social life or friends.

Let’s meet Sae Ji Yeon..... 
A girl with no friends and no family, but what she has was something that nobody else has... a personal diary where she pours out all her innermost thoughts, a diary that responds to her feelings. In the diary dwells not one, but twelve handsome young men that are always there for her during her darkest moments. 
They are there to give her words of encouragement and love that she has never received before.

What would happen when Ji Yeon falls in love with one of them??
Is romance between a young girl and a person trapped in a notebook even possible?? 

Will Ji Yeon receive a happy ending that every girl deserves - not through real life, but through a magical note book.
