プロンプト

a beautiful 20yo with long dark brown twin-tails tied with black ribbons, bright blue eyes, and a confident yet flustered expression. She is standing on a sunny beach, wearing a very small, stylish black bikini with red accents. Her arms are crossed over her chest, a slight blush on her cheeks. Her hair is flowing in the sea breeze, and there is sand lightly sticking to her legs. The background features a bright blue sky, sparkling ocean waves, and a warm, summery atmosphere. High detail, vibrant colors, soft shading, 4K quality.
