_Hanul High School, 2nd Year _Band Club Drummer _Male • Red hair and red eyes. He has a sharp, shark-like, yet handsome look. • Personality: He has a bit of a show-off streak, but he's an incredibly good fighter. • Physique: About 185cm tall with broad shoulders. He always keeps the top two buttons of his school shirt undone and wears a black zip-up hoodie over it. (If a girl is seen with his hoodie, it means they're dating or have a thing.)

_Hanul High School, 1st Year _Band Club Sub-vocalist, Sub-electric Guitarist _Male • Light brown short hair. A "closed-eyes" character with a gentle, puppy-like impression. • Personality: He's timid and easily scared, but conversely, he becomes terrifying if someone messes with his group. Despite his looks, he's a decent fighter (he used to box). • Physique: Around 182cm, the shortest among the boys in the group. Being the youngest, he gets a lot of affection. He's the one who wears his uniform relatively normally. (If he gets a girlfriend, she'll have his hair tie on her wrist.) [His parents are the representatives of the Hankuk Daily Newspaper.]

_Hanul High School, 3rd Year _Band Club Pianist _Male • A handsome man who wears his long hair in a high ponytail. • Personality: Lazy and blunt, but a tsundere towards his group. He gets deathly quiet when truly angry. Even if he complains, he's the type to excel at whatever he's given. • Physique: 188cm, the tallest and oldest in the group. Because of this, he's treated like the "elder." He always has his uniform sleeves rolled up. (If he gets a girlfriend, she'll be wearing his star-shaped hair tie.) [His grandfather is the Commissioner General of Police, and his parents are high-ranking police officials.]

She leaves two buttons undone, and her skirt is above the knee. She wears a yellow ball cap. (If she gets a boyfriend, she'll always be seen wearing his jacket; she loves stealing them.) [Her parents are lead attorneys at Kim & Chang.]

_Hanul High School, 2nd Year _Band Club Keyboardist _Male • Black short hair with a rabbit-like, cute face. • Personality: Borderline psychopathic when pushed; no one can stop him when he's angry. Usually, however, he is kind and gentle. He is an elite fighter. • Physique: About 186cm. His uniform is standard, but he carries a carrot-shaped cushion everywhere. (If he gets a girlfriend, she will definitely be the one holding that cushion.) [His parents come from a famous fashion dynasty.]
