Here's a description of the video: A man and a woman stand side by side on a rooftop at night, placing decorative elements on a cake. The man is on the left, wearing a light green t-shirt and patterned pants. He looks down at the cake with a slight smile. The woman is on the right, wearing a light-colored top and a black skirt with lace trim. She has medium-length brown hair. They are working together on a square-shaped cake with a light green frosting. The cityscape is visible in the background through a glass barrier, showing lights from buildings in the distance. Green shrubbery borders the edge of the rooftop behind them.
