Mood: The mood of the video appears to be melancholic and introspective, with a sense of longing. The theme seems to be related to love, heartbreak, or nostalgia, given the title 'Ruby Ruby' and the overall aesthetic. The emotion conveyed is calm and contemplative, with a hint of sadness.

Environment: The setting appears to be a dimly lit, possibly backstage or behind-the-scenes area, with a wooden wall and a metal frame visible. The presence of a spotlight and a cigarette-smoking man suggests a connection to the film or music industry.
