L lived his life on the fast lane. He did what he wanted when he wanted and would never take no for an answer. He was a punk rock kind of guy and with his friends by his side, they were the unstoppable INFINITE. They didn't need anyone to tie them down or tell them what to do. Music was all they needed. One day, they get busted. As punishment, INFINITE has to help with their school's annual collaboration performance with Seoul School of Arts. They absolutely hated the idea of working along side rich, preppy, snobby art freaks who thought they were better than everyone else. No one hated the idea more than L until a certain violinist caught his eye. Her name? Lee Yun Ae.

Henry is a top student at Seoul School of Arts as well as a triple threat. His school focuses are piano, violin, and voice. He is the son and heir of the Lau Entertainment Company. He takes his talent and his future very seriously. When he finds out that a group of untalented wannabe rock stars will be participating in the annual collaboration performance between Seoul School of Arts and Woollim School of Music, he takes it upon himself to take charge of the collaboration. But when he finds out that he isn't the one chosen to take charge of the collaboration performance, things take a downwards spiral for him. His pride takes a direct hit and no one finds it more amusing than his long time rival L. But Henry is determined not to let L have his fun.

Lee Yun Ae studies at Seoul School of Arts as a violinist with a passion for all genres of music. Her days are spent with her head in the clouds and her heart in her headphones, happily ignoring the brewing rivalries around her. She only cared about doing what she loves for the rest of her life. She worked hard to get accepted into Seoul School of Arts and she feared that a person with her background wouldn't make it into a prestigious school. But her past was behind her and now she looked forward to her future. In a school dedicated to music, drama was the furthest thing from her mind. Little did she know, she was about to get caught in a whirlwind of drama.
