In Seoul, there was a famous high school named Seoul Performing Arts. It was well known because of its facilities and talented students there. It was an art school so singing, dancing, painting and more art works were their subjects beside general subjects.

They also had beautiful uniforms for their students

Not forget to mention that this school was very expensive that's why only rich people could enter this school. So did a girl named Jung So Yeon, she came from a rich family, his father owned many resorts and hotels. It sounds like she had a perfect life but actually no she wasn't. She was a fat girl, she ate a lot and didn't have any interest on any other thing beside her food. Her grades at school was okay but she never enjoyed school days because no one wanted to be her friend except one girl named Da Eun.

 And here is Da Eun, she was a bubbly and cheerful girl. She was the type of a person that how bad her personality is you still can't hate her. Her parents died when she was ten, and she currently lived with her brother, Lee Taemin

 There was also a guy named Oh Sehun. He was said to be the school's flower boy because of his pretty face but his cold aura often be mistaken as rude. Many girls had fallen for him included So Yeon, not because Sehun was good looking but because he..Oh Sehun..was like So Yeon's guardian angel.

And that's how the story began. Two different people, the handsome one and the beast one. Would they end up happily ever after? just like what fairy tales ended? but then..this is not a fairy tale..everything could happen, everything could be changed.

"I'm changing now because of you."

"I realize that you're the one who fill the empty spot in my heart."
