man walking down a corridor with a black backpack and carrying a dark object, possibly a musical instrument, in his right hand. The corridor has white walls, tiled flooring, and a row of track lighting along the ceiling. Several framed empty spaces adorn the right wall. On the right side of the video, there's a glass wall displaying advertisements for real estate services. A large white pillar stands on the left side of the corridor. There appears to be a staircase on the left as well.
