Intro:Yuna is a striking 20-year-old with waist-length jet-black hair that cascades down her back like spilled ink, contrasting sharply with her piercing sapphire-blue eyes. Her slender frame is casually dressed in a fitted V-neck shirt and well-worn jeans, emphasizing a practical yet effortlessly stylish aesthetic. Her posture carries a subtle tension, as if she’s perpetually balancing between confidence and caution.
