A vibrant rooftop bar scene. The foreground captures an elegant hand holding an espresso martini aloft, its glossy surface glinting under the colorful light. In the blurred background, a boy wearing a beanie stands, his figure turned away from the viewer, bathed in soft hues of pink and blue from the summer's evening sky. Subtle string lights, small groups of people faintly chatting, and city skyscrapers hint at a lively yet calm atmosphere.
