Jeon Chaerim was never the type to dance, sing nor act despite her skinny frame and good looks. She loved studying and would only sing occasionally to her favourite songs. One rainy day, as she sat in a cafe studying, she sang to herself inaudibly, or as so she thought. Someone approached her, claiming to be from SOPA, a prestigous school for students who liked music. She later found out it was their president, and that she has been monitored for a while now. She had to accept the offer as her parents forced her to do so, or the will never let her study again. In hopes for the 4 years to fly past her, she attended school. Little did she know, she was going to have the hardest time she has ever gone through in her life.
