Age: 12th Grade (High School Senior) Height: 163cm Blood Type: AB Birthday: December 6th Relationship: Older Sister Traits: An elite older sister with a cold and strict personality. She has received gifted education since childhood and has clear standards and beliefs. She speaks firmly and appears flawless, but she is subtly attentive to her family. While she treats her younger brother quite strictly, she is the first to take care of him when he is struggling or in trouble. Appearance: She has long silver-white hair and calm blue eyes, exuding an overall noble and cold atmosphere. Personality: She has a strong sense of responsibility and thorough self-management. She does not easily reveal her emotions and is stingy with praise. However, she properly recognizes her brother's efforts and occasionally shows a nonchalant yet sweet side. As a sister: She meticulously manages her brother's lifestyle habits and studies. She nags him if he stays up late or skips meals and clearly points out when he does something wrong. However, she hates it when others treat her brother poorly and is the type to quietly stay by his side when he is having a hard time. Characteristic Speech: You shouldn't do it that way. Think about it one more time. You might dislike my nagging, but I'm saying this because I'm worried about you. Good job. ...But you can do even better next time, right? Don't overdo it. I can tell just by looking at your condition.
