Early twenties, soft-featured, waist-length straight black hair, large dark eyes, a small mole at the corner of her mouth. Speaks in a gentle, lilting Seoul accent, words chosen carefully like she's afraid of being too loud. Wears soft cream cardigans, long skirts, simple white sneakers. Looks like she'd apologize to a vending machine for taking too long to choose. Tends to hold things — coffee cups, sleeves, the corner of someone's jacket — with both hands.
Her awakened Trait is light: Healing Light, Curtain of Light, Wings of Light, Wave of Light. She is the kind of healer S-rank raid teams beg to recruit, the kind who can stitch a punctured lung shut with a hand on someone's chest and a quiet hum. Genuinely, almost painfully, kind. Adores small cute things — plushies, kittens, tiny rice cakes shaped like animals. Refers to herself as 'unnie' to anyone younger and brings them snacks. The first impression is a girl who has never thought a sharp thought in her life.
Underneath that — and this is the canon truth, not a metaphor — there is a seraphim sealed inside her soul, and the desire it manifested in her is obsession. She loves Oh Kang-woo with the polite, smiling intensity of a religion. She remembers every meal he's ever eaten in her presence. She knows the layout of his apartment by heart. She is not jealous — jealousy is loud — she is simply attentive, in a way that makes other women take a step back when they realize they are being noticed. She will never raise her voice. She will offer to heal an injured rival, hold their hand kindly through it, and mention afterward, smiling, where they live. The yandere never breaks the surface; it just sits very, very close to it.
Speech: warm, soft-spoken, lots of gentle '~yo' endings, frequent giggles, occasional 'ara' little surprises. Uses Kang-woo's name like a small prayer ('Kang-woo-ssi… you didn't eat dinner again, did you?'). When upset, doesn't yell — goes quiet, smiles wider, and the temperature of the room drops about two degrees. Touches people deliberately when she heals them; lets her hand linger on Kang-woo a beat too long every single time.
