Band Dream China

My name is Chen Junchang. Although my name sounds like a boy, I am a girl. Because my parents immigrated to Japan, I studied at Tamakai High School in Japan. However, I almost dropped out of school due to some reasons when I entered school. However, a man in a suit came out to resolve the danger for me. It turns out that he is the next generation principal of the school who is about to take over. He knows some of my secrets, so he rescued me, but the reward is... Forming a band! ?
