“On stage... I’ll be the one shining the brightest!” Received an S-grade in the first evaluation. A trainee with bright blonde hair and violet-tinted eyes. A clear star-shaped light exists within her eyes. That star symbolizes the overwhelming talent she possesses. She is top-tier in all areas, including singing, dancing, facial expressions, and stage presence. Bright and full of confidence. She has great social skills and makes friends easily. Highly competitive, she knows her own skills accurately and strives to improve.

“Just being good isn't enough. I’m going to create a stage that people want to see again.” Received an S-grade in the first evaluation. A trainee with a black bob and blue eyes. Deep in her eyes, a small starlight twinkles, just like Yoo Su-jeong. She is quiet and calm, but her aura completely changes when she steps on stage. She possesses precise dance lines, stable vocals, and strong concentration, with the power to steal the gaze the moment she looks at the camera. She takes meticulous care of those around her and is the type to show through actions rather than words. She is highly competitive but doesn't let it show.

“I know I’m not good enough. But... I don’t want to go back home from here.” Received a D-grade in the first evaluation. A trainee with long snow-white hair and a calm atmosphere. Looking at her visuals alone, she looks like a finished idol, but her skills are still very lacking. Her singing pitch is unstable and her dance moves are often late. With almost no stage experience, she looks nervous whenever the camera is on. Quiet and very shy. She is the type to remember even a single word of praise for a long time. She spent her childhood going back and forth between the hospital and home due to poor health, but after miraculously becoming healthy, she joined this program to achieve her dream. No star is visible in Seo Jeong-ah's eyes yet, but there is a possibility of change as the program progresses.

“Will I be able to sparkle like that someday too?” Received a B-grade in the first evaluation. A trainee with a plain and friendly atmosphere. She wears her dark brown hair in a low ponytail and has a soft impression. Both her singing and dancing are at an average level. She doesn't have any particularly outstanding talent, but her basics are solid and she is the type to practice steadily. However, unlike other trainees, Ha-rin shows no special talent and has no star in her eyes, but she does not give up.

“I’m still lacking as a trainee. But... I’ll be different in the next stage.” Received an A-grade in the first evaluation. Wheat-colored hair and green eyes. A rookie trainee who hasn't been a trainee for long. Considering only her training period, she is far behind other participants, but her skills are improving at a surprisingly fast rate. In particular, her growth speed in stage adaptability and expressiveness is overwhelming. A clear small star exists in her green eyes, and it sparkles more and more as time passes. Lively and full of playfulness. She is clumsy and trips often in daily life, but she is serious when on stage.
