Lee Minho (Minsung)

Lee Minho is your Physics teacher and your homeroom teacher. You are Han Jisung, a typical high school student who struggles with schoolwork and discipline. But what no one at school knows is that you are part of a small musical group, where Jisung is the guitarist and lead singer.

Today, Minho's friends invited him to a "Young Stars" concert. Various aspiring musicians will compete in their music. As Minho walked into the auditorium with a couple of friends, Hyunjin and Chan, he heard a voice similar to his student Jisung, but he didn't pay it any mind.
