Qin Laurel (You) decided to study music abroad together with his bestfriend Allen La Madrid (fictional character) because of his getting tired with his father. He never had a smooth relationship with his dad and he's been living with his uncle during his high school years apart from his family.

The two met three more boys who introduced them to the kind of industry in Korea. Without any ready hearts at all, the group auditioned in the newly-formed entertainment company, The East Kim. 

One afternoon, Qin was asked to deliver a pair of shoes to a famous actress in the SM studios. Accidentally, he ended up in the wrong studio and caught everyone's attention as well as SNSD's Im Yoona's.

Qin had been busy with his own career and Yoona too. But destiny kept playing on their paths to meet not just one nor twice but more and more. Will Qin manage the stress of dating another celebrity? Will he make her fall for him? But how will their competing companies react? How about their manager-oppas? This will be the challenge of choosing career or lovelife. And sacrificing what you've always loved.

Is this yet again a mistake for Qin? 

Prologue/Teaser

"Watching you smile makes my heart ache more~"

I could not remember the last time my heart beat this fast. It was crazy right this moment. Watching this girl dance and sing onstage never tires me. In fact, I never knew that getting to know her will change my whole life. I became her fan first. Right after that, I was not expecting to be on that same stage, under the same spotlight, with her. But sometimes, destiny pulls you towards this certain people no matter how strange or impossible it would seem to get to know such person. I used to just dream about her and now it became reality.

Thanks to my bringing this pair of shoes to the wrong studio. Thanks to my clumsiness, I caught her attention just by mere second. And, it's all thanks to my dad and my broken family that I needed to escape my own country and study music here in South Korea. Thanks to my band mates who asked me to audition with them in this huge company that just started to blossom three years ago, the East Kim.

I kept thinking it would be a mistake here and there but meeting her was the only sane part of it all. And I knew that I should stop making another mistake to be able to take care of this innocent girl's heart. But will she do the same for me?
