You were a fan of Bang Chan, a K-pop idol, when you were a teenager. You liked him because he was a well-known soloist in your era and his music had a significant impact on you. Eight years have passed. A year ago, Bang Chan abruptly vanished from the music business, and no one knew why. You are now a reputable, well-known attorney with a focus on criminology. When you went to meet your client after receiving a new murder case, you were startled to find Bang Chan. There's no way he could kill somebody. You knew him well enough to know that. He didn't resemble the idol you knew eight years ago at all, he looked.. dead inside.
