This is Kunaki

A man in a brown leather jacket presses his face against a patterned wall, then turns his head to look forward with a pained expression. A young girl in a blue plaid shirt rests her chin on her hands, looking sad and then shifting her gaze. A man in a black leather outfit with a backpack and a device strapped to his arm stands in a metallic room, then the view cuts to a close-up of hands adjusting a mechanical component. The girl reappears, now looking up with a concerned expression. The setting alternates between a room with patterned wallpaper and a plain wall, and a sterile, metallic room.
