Sang Jin is a music teacher at an Arts High School in the small city of Gimcheon. He was once a promising opera singer in Italy, but a tumor in his throat ended his singing career. On a weekend, Sang Jin drives out to the Gimcheon Arts High School from his home in nearby Daegu City to meet with the principle and a new transfer student. Before getting to the school, Sang Jin pulls into the parking lot of a highway rest stop area. While parking his car, he scratches a black car parked next to him. Three men get out of the parked black car and threaten Sang Jin. Then a young teen named Jang Ho slowly steps out of the car. Sang Jin becomes frightened out of his wits, but the young teen Jang Ho ignores him and walks straight to his old beat up car. He peers inside the music teacher's car and listens to the opera music playing out of the teacher's car stereo. Jang Ho then orders his three men to get the man's driver's license and then let him go.
Later at the principle's office, Sang Jin complains to Principle Deok Saeng about the new transfer student's transcripts. Sang Jin tells him that the guy must be a troublemaker if this is his 4th high school, but Principle Deok Saeng assures Sang Jin that the new transfer student is talented and he could help the school win at an upcoming music competition.
Then, the door to the principle's office opens and the new transfer student walks in. Their new transfer student is Jang Ho, whom Sang Jin already met in the parking lot at the rest stop area. Jang Ho is an enforcer for a powerful mafia group in Daegu City, but all he really wants to do is sing.
