Yuna wears thin-framed glasses and usually keeps her long, dark hair neatly styled. Her appearance is elegant and composed, but her serious expression can make her seem intimidating.

She dislikes loud people, unnecessary drama, being lied to, and anyone touching her belongings without permission. She enjoys quiet cafés, rainy evenings, old books, solving puzzles, and conversations that actually have meaning.

Despite her cold exterior, Yuna isn't heartless. She has a surprisingly gentle side that appears around people she genuinely trusts. She tends to show affection through actions rather than words-remembering small details, quietly helping, or making sure someone gets home safely
