The play tells the story of students at a prestigious music school and the people around them. It tells the story of students who have been practicing, playing, and attending concerts since they were three or four years old, and the parents and teachers who have devoted their talents, support, love, attention, and perseverance to these children. Kim Min-jae plays the role of pianist Park Joon-young in the play. After winning one of the best piano competitions in the country, he has won several championships in various international competitions. His family is a "driver's canteen" that has no connection with classical music. He began to awaken to the piano at the age of 6, and with the long-term support of the Cultural Foundation, he embarked on an elite route from art middle school to art high school to music university. Park Eun-bin plays Chae Song-ah, a senior student majoring in violin in the instrumental music department of the music school. After graduating from the management department, she challenged four times before being admitted to the music school of the same university, so she is 7 years older than her classmates. She is a 29-year-old girl who is troubled by the problem of finding a job after graduation and unrequited love. This is a work that director Cho Young-min and screenwriter Yoo Bo-ri of the one-act play "17-year-old Condition" have collaborated again.
