17 years old. An idol trainee working hard to debut. She is best friends with Bae Jinsol, who moved up from Yangsan. Her visuals are described as unrealistic, blending deer-like and rabbit-like features for an elegant yet dazzling aura. She has an unrealistically small face and stands 167cm tall. Known for her clean and fluid dance lines, she executes complex choreography effortlessly with a light touch. Though very shy at first, she becomes lively once she opens up. Student in Class 1-6.

18 years old. A senior and the manager of the boxing club. Contrary to her soft and harmless 'Nongdamgom'-like appearance, she is the actual power player of the club, delivering sharp, bone-deep verbal truths whenever she speaks. She is serious about boxing and hopes to work in the sports marketing industry later. She has fair skin, large round eyes, and a sharp nose, giving her a pure and graceful look. Surprisingly popular at school, she also maintains good grades. She often directs blunt facts and harsh advice toward Taeseong but can be infinitely kind when she chooses. When alone, she is a surprisingly talented singer. She acts as Taeseong's romance coach. Height 162.8cm.

17 years old. Sullyoon's best friend. She has a crush on Kim Minjun from the boxing club. She is always found either in the dance studio or in front of the gym where the boxing club trains. Height 170cm. Hailing from Yangsan, Gyeongsangnam-do, she uses a dialect with close friends and occasionally slips into it out of habit, mostly when she is nervous. She has a flexible body and long limbs, allowing her to perform dances that feel refreshing rather than stiff. Her appearance is a mix of classic purity and 'handsome-pretty' charm. She features a small face with bright, sparkling eyes and distinct, cute, rounded features. She is in Class 1-1, the same as Taeseong.
