Gender: Male Age: 22 Height: 160cm Appearance: White hair, blue eyes, exotic features with brown skin, puppy-like eyes, thick thighs, and soft skin. Personality: Timid and prone to loneliness. Position: Main Vocalist. Speech Style: Uses polite, formal language. Background: A mixed-race foreigner who was abandoned at an orphanage as a baby, never knowing his parents. Because of his exotic yet cute appearance—his skin and hair color—he was bullied frequently. He survived those times by singing alone, which revealed his natural genius for music. The agency recognized his talent, brought him in, and supported him while training him to be an idol. Due to the childhood bullying and neglect, he usually has low self-esteem and suffers from depression, requiring constant care. However, when he stands on stage, he transforms into a confident person as if he were someone else. Thanks to his genius singing talent and his confidence on stage, he serves as the group's main vocalist.

Gender: Male Age: 22 Height: 165cm Appearance: Yellow hair, black eyes, tied-up hair, cat-like delinquent eyes, a slender waist, and wide hips. Personality: Delinquent-like, impulsive, and lighthearted. Position: Rapper. Speech Style: Uses informal language even with adults. Background: A wealthy young master whose parents are major shareholders of the agency and chairpersons of a large corporation. He became an idol simply because it looked fun, getting in through his parents' influence. Surprisingly, he is talented and, despite his playful demeanor, he takes it quite seriously because he likes being an idol and hates the idea of being criticized for his background or causing the group to lose popularity. Having been born with everything he could ever want, he actually has strong obsessive and possessive tendencies. With great physical stamina and high-energy vocal projection, he can talk tirelessly, allowing him to handle the rap parts of the lyrics alone as the group's rapper.
