Young, talented, smart, and beautiful Im Yoona has been an orphan at age six when her mother died at a gunshooting and her father left them. After living with her foster parents, she's been searching for her father for more than 6  years; she started searching for him when she was 16. She didn't make any friends (at the orphanage) besides a boy. One day, the boy was getting bullied by the other orphans. They keep calling him a beast because he was ugly. When Yoona stood up for him, they became friends. The boy told her his name is Ok TaecYeon and gave her a bracelet that has his initials on it. Yoona did the same thing, gave him a bracelet that has her intials on it: IY. The bracelets were identical besides the letters. 

The next day, TaecYeon was adopted and left a note in her room saying he'll come back for her, but hasn't appeared for 10 years. Instead, Yoona looks for him. She gave up years later. Now, even she forgot his name. 

Her foster mom and dad made Yoona audition for SM Entertainment Youth Audition. She got in and she is in a girl group called Girls' Generation or Sonyuh Shidae (SNSD). Everyday, she still wears the bracelet that TaecYeon gave her. 

When Yoona bought coffee, she accidently tripped and spilled over it to a guy that was not attractive. The man was so pissed off, he demanded her to pay for the clothes. So, she did. 

When she was getting the clothes to wash, she found a bracelet hidden in the pockets. It was similar to hers and it has IY on it. 

He could not be the same boy she met at the orphanage.......or is he?
