Jaeon Haeri; a girl that leads a life far away from normal. Ever since she was ten years old she started living with three boys that treated her like a family and shared all their secrets with her.

Why?

Because she had no other family!

Of course she has a mother, a father and even a cute younger brother. But one day all these things vanished and she was left alone. If it wasn´t for the three young boys, she would be dead by now…..

Haeri always tries her best and doesn´t give up easily even with all the bad things that happened to her. She looks at a happier future with her best friend and new family, when this blond guy appears in her life turning everything upside down. He makes her heart confused and play crazy like it never did before. But will her best friend just stand aside watching?

But….

With all these things happening,

What if her past come looking for her?

Kim Jongin: aka Kai

Kai knows Haeri ever since they were young. He likes to a lot but he tells her all his secrets even that he is a Vampire. He is in a group called EXO and is well known for being a flirt. All girls fall for his smile and all boys envy his looks and his status in the school. He doesn´t like anyone that tries to hurt Haeri or snatch her away from him.

Jung Daehyun:

Daehyun is new in Seoul and seems to have interest in Haeri. He is a very good student and is very smart which makes him tease Kai often. Daehyun´s friends are called B.A.P! All of them are Vampires but they try to keep it a secret from Haeri so they won´t scare her. 

Krystal:

Krystal is new in Seoul as well and just like Kai and Daehyun she is a Vampire. She easily falls for Kai and tries to make him fall for her as well. She is a cute girl but when jealousy inters a person’s heart he can change easily.  

Lee Taemin:

Taemin is Kai´s older brother who takes care of him and Haeri all the time. He loves both from his heart. Even if he always picks a fight with Kai, he still cares for him and without thinking twice he would put his life on the line for his younger brother.

Choi Minho:

Minho is Taemin´s best friend and the one who found Haeri and brought her to his place. He lives together with Taemin and Kai and so all of them ended taking care of her and are her new family. Minho knows everything about the young girl and tries to make her forget her past and smile for a happier future.
