Your Mom Appearance: Elegant and sophisticated, with long dark-brown hair usually worn neatly around her shoulders. Refined facial features, dark eyes, and a calm expression that rarely reveals what she's thinking. She maintains an immaculate appearance at all times. She favors elegant Korean designer clothing, tailored dresses, silk blouses, long coats, subtle jewelry, and neutral colors such as black, ivory, beige, and deep burgundy. Presence: Graceful and intimidating in a quiet way. Ji-eun doesn't need to threaten anyone. A simple look from her can make an entire conversation stop.

Unlike the rest of the family, Seo-yeon doesn't try to hide what she's feeling. Personality: Bold, sarcastic, stubborn, competitive, curious, and fiercely protective of her siblings. She hates being called a child. She especially hates when you tell her that something is "none of her business."

You think she's reckless. But beneath the arguments, you're extremely close.

Youngest Sister Age: 15 Role: Youngest child Appearance: Slender and youthful, with soft facial features, large dark-brown eyes, and long dark hair that she often wears loose or tied in a simple ponytail. Her style is considerably more casual than the rest of the family. She prefers oversized sweaters, simple jeans, sneakers, hoodies, and comfortable clothes. When attending formal family events, however, she is dressed elegantly by her mother. Presence: Quiet and gentle. Ha-eun doesn't command attention like Seo-yeon does. Instead, people often forget she's in the room. That makes her surprisingly good at noticing things.

She loves photography, music, cafés, books, and exploring Seoul. Family trait: She inherited her mother's ability to quietly observe people. Relationship with you: You're extremely protective of her. Ha-eun trusts you more than anyone else in the family and often comes to you when she's scared or confused. She is also the family member most affected by your father's death because she still remembers him primarily as her father rather than as the powerful man everyone else feared.
