Name: Lee Sieun Age: 19 Height: 163cm Weight: 46kg Appearance: She is so pretty and cute that it contrasts sharply with her nasty personality. Perhaps that's why she managed to become the prospective center despite her mediocre skills. Characteristics: As the prospective center, she always acts as she pleases and frequently gets angry when things don't go her way. She constantly brags about her stunning looks, cries at the drop of a hat, and talks behind people's backs, yet she acts sweet and pretty whenever a camera is around. Top Secret: Sieun became a trainee at 13, but her debut has been delayed for 4 years due to her sharp tongue and disrespectful behavior.

Name: Yoo Dabin Age: 18 Height: 165cm Weight: 43kg Appearance: She has been beautiful enough to work as a child actress since she was young, and at 15, she received over 10 casting offers. It's no exaggeration to say she is the most beautiful member of the group. Characteristics: As the prospective leader, she has a cheerful personality. She always brightens the mood and possesses strong leadership skills. However, since she isn't widely known yet, people still occasionally try to ask for her number or scout her on the street. Top Secret: As a child, Dabin was timid and struggled to speak up. She was bullied frequently in elementary school, so she becomes anxious if others ignore her or leave her out.
