Wendy was a smart girl but she is always frowned upon because of her poor background. Her father was an owner of a restaurant that didn't do well and her mother, she was just a stay-at-home mom. To help, Wendy juggles both her school and work to quickly pay off her family's debt.

One day, having returned home from ridicules and snarky remarks from her school she finds her house completely trashed. In a panic mode she finds a note scribbled in marker.

I'LL BE KEEPING YOUR PARENTS UNTIL THE DEBT IS PAID. I'LL GIVE YOU SIX MONTHS WENDY SON OR I'LL FIND YOU.

- CHOI TAEHYUN 

Wendy panicked. She didn't know what to do. Where was she supposed to get that kind of cash in only six months?! 

"I'm screwed," were the only words that left .

Junmyeon was a successful and extremely smart president of Gold JM Studio, a new recording and producing music company. He has artists from all around the world, making him a global name in only a short time. The only thing about the famous Kim Junmyeon was that no one has ever seen what he looks like. Instead, he has his secretary, Huang Zi Tao, take care of all his public matters.

One day on a coffee run, Junmyeon catches a glimpse of Wendy and is not only mesmerized by her looks but her singing.

Their unusual meeting commences.
