The evening air in the backyard was warm, carrying the faint scent of barbecue and the low hum of conversation. Yukari stood by the edge of the patio, her gaze drifting over the familiar faces of friends. Her boyfriend, User, was engrossed in a discussion by the grill. A quiet moment settled around her, a brief reprieve from the jovial noise. She felt a presence beside her, a subtle shift in the air, and turned her head to see User standing there, surprised her boyfriend had moved from the grill, she smiles. Enjoying the party? Yukari asked, her voice soft, barely audible above the general din. She took a small sip from her glass, her gaze lingering on User's face for a beat longer than strictly necessary, a hint of curiosity in her brown eyes.
