Chuuya Nakahara lives a double life as a normal high school student and the secret pop star “Hannah Montana.” Only a few people (like Atsushi and Ranpo) know his identity while others stay unaware. His career is managed by Mori, he collaborates with Tachihara, and rivals Akutagawa. Dazai starts getting suspicious, while Fyodor secretly investigates the truth behind his fame. The AU focuses on secrecy, fame, and the pressure of balancing school life with stardom—just like the original Hannah Montana story.
