Kim Ryeowook was that kind of person who had gotten bullied many times, but doesn't do anything back. And him not fighting back gives the bullies the advantage to bully him more. One day, a new student came into the school and Ryeowook thought he was different from the bullies but once he saw his appearance, he knew he thought it all wrong. The new student was his previous school's bully, that's why he was transferred here. And the only way Ryeowook wanted to stop getting bullied is to change himself.

One day, Ryeowook ran away to America to change his style of wearing clothes and using contact lens instead of glasses. He had a new hairstyle and he bought different kinds of stylist clothes. A year later, he went back to Korea and when he came back to school, as he stepped in, everyone stared at him and he smirked. He had a totally different personality. Instead of the softie and weak personality, he had this bad boy image he wishes to maintain.

As he walked to class, he saw the new student again. That was when he remembered his name: Cho Kyuhyun. As he walked past Kyuhyun, the cologne Ryeowook used could be smelt from the breeze as he walked past the new student. He watched as Ryeowook walked past without any fear and he smirked at that.

"Looks like our Ryeowook has changed."
