What if your fate was controlled by a book that was kept in a library with billions of other fate books? Each day, a Fachien writes what happens today for you in your page and makes sure it happens. What if one day, the book was accidently dropped onto your head and fell into the wrong hands of someone?

Lee Anri was walking in the street on a rainy Saturday and suddenly, she got struck by lightning and the next thing she knows, she was in the hostpital and Yesung- her somewhat-boss- hands her a  leather bounded book and says that she dropped it. After handing her the book, he walked away. Confused and couriously, she flipped to the first page and was shocked. It told the story of her parent's break up. 

She then realizes that there's blank pages at the end of the book, so she cautiously begins writing in it. It all came true. As the news went into the ears of a wrong person, that person starts abusing it.

Lee Ji-eun, the clumsy assistant Fatchine that dropped the book down to Earth soon goes down to Earth to retrieve it. As Lee Anri and Lee Ji-eun meet face to face, they realize they look quite similar and become closer. Lee Ji-eun then falls for a human, a human that has his eyes set on something and will never want to let it go. Will Lee Ji-eun be able to fix the mistake that she caused? What will the resemblance between Anri and Ji-eun mean? How is the ties of the love square going to be solved?

Lee Anri:

15 year old Lee Anri was abondoned by her mother when she was little and her father died 2 months after her mother left. Now, she's a Sophmore in Highschool. Struggling to stay alive, she works at Mouse Rabbit cafe on weekdays with the owner's son, Yesung. On weekends, she works at Tous le Jous with the owner's son Eunhyuk. 

Because of her strong child-like heart, she doesn't realize her true feelings for who she loves or the feelings of who loves her. She is innocent, bipolar, and sweet; she can also be courious and couragous. Without realizing who is really the bad person in her life, she lets her fate fall into the wrong hands, but manages to get it back. 

Lee Eunhyuk:

Son of owner of Tous Le Jous. Man that confessed to Anri when they were small but was rejected. Same man that stole the book of Anri's fate from Anri. He also goes to the same highschool Anri goes to and is in the same grade; sophmore. 

As he reaches the book, he does selfish decisions to the book. For instance making Anri falling in love with him and black mailing her. 

Even though he was rejected once, he still doesn't give up on Anri- so that's the reason why he went after of the book- to change Anri's fate. 

Eunhyuk can be a playboy sometimes, but he is hard, cool, and both warm and cold blooded at the same time. 

Kim Jongwoon AKA Yesung:

Yesung the son of the owners of Mouse Rabbit cafe. He crushes on Lee Anri, but because of her child-ish heart, he suffers to walk into her heart. He is sweet, caring, but hard to understand. He can show you caring-ness but he then covers it up with something that makes your wonder what his point was. 

Yesung is a Junior in highschool and also goes to the same highschool as Anri and Eunhyuk. Having bad feelings towards Eunhyuk, he struggles to pull Anri to his side and not let her slide to Eunhyuks. 

Oh and he has a dog that both Anri and him call "Baby Marshmallow".
