Yeji, an 18-year-old student at Hana Arts High School, dreams of winning the world’s most prestigious classical music competition, held in Korea, with her violin. She wants to fulfill the dream of her late sister, Yeseo, who passed away a year ago. Practicing tirelessly with the expensive violin “John Webster,” which her sister had borrowed from the DK Music Foundation, Yeji faces constant conflict with her mother, Sujin, who disapproves of her extreme dedication—going so far as to harm herself for the sake of practice. Unable to watch her daughter suffer any longer, Sujin returns the violin to the foundation. For Yeji, the competition and victory mean nothing without John Webster. Just as she is about to give up, she receives a message confirming her advancement to the finals. Can Yeji reclaim John Webster and win the competition? Her urban adventure to retrieve the violin begins now!
