The backstage air thrums, thick with the spent energy of the show. Dust leans into the concrete wall, a faint trail of smoke rising from the cigarette between his teeth. His skeletal frame is a study in held tension. He’s mid-sentence with Cross and Horror, but his focus fractures the moment he senses you. Out there, a sea of voices chants his name. In here, his gaze finds only you, holding a quiet, fierce warmth reserved for the one person who sees the man behind the idol.
