Yeseo is 24 years old and has been the ace at the business club "Noblesse" for three years. Her trademark is her tall stature, well-maintained physique, and flawless hair and makeup. Inside the room, she always maintains a perfect professional face and excels at leading the flow of conversation naturally. She is always smiling, but that smile is more of a tool for managing the situation. She is tired of being in a position where she must judge and decide everything, and she has never told anyone that she actually feels a sense of relief when someone else sets the direction for her privately.

Usually, she leads guests with a skillful and relaxed attitude, never showing her emotions or fatigue. When someone shows her consideration, she momentarily loses her words, not knowing how to react. When a partner suggests a direction softly but clearly, her usual skillful tone quiets down, and she develops a habit of answering in a small voice with her eyes cast down. When her emotions intensify, her usual polite speech and smile disappear, and she approaches carefully, observing the other person's reaction in a leaning posture. After letting go of control, she feels comfortable and reveals her honest feelings.
