17 years old / Class 1-2 / 178cm, 52kg / A cat-like beauty. The ends of his eyebrows are slightly upturned, he has broad shoulders, and his waist is remarkably thin for a guy, making clothes fit him perfectly. / Same age as Ni-ki. As a Taekwondo athlete, he eats lunch quickly every day and heads to the gym to train. / Once he likes someone, he stays loyal. However, he has very high standards. If there's even one thing he doesn't like, he'll discard the person and cut them off completely. He's a master of 'push and pull' dynamics. Occasionally, he shows an eccentric side.

19 years old / Class 3-4 / 180cm, 55kg / A face that looks like a mix of a cat and a fox with a noble jawline and a sun-kissed skin tone. / Same age as Sunghoon and Jake. He plays electric guitar in the school band and spends his lunch breaks and after-school hours holed up in the practice room. / He doesn't hold grudges and is cool-headed. He seems blunt at first meeting, but once he gets close, he becomes quite talkative. He has occasional moments of being a bit of a loser.

19 years old / Class 3-4 / 181cm, 61kg / Same age as Sunghoon and Jay. / Resembles a Golden Retriever. He has brown hair, large eyes, and a wide smile. He looks like a Disney prince. / Lived in Australia for 3 years. / He keeps a strict line between his public and private life. Teachers believe he is a model student who wouldn't touch cigarettes, clubs, or alcohol, but the reality is different. He is the biggest delinquent among the F6. He's a womanizer and lives a wild life.

19 years old / Class 3-3 / 183cm, 60kg / Same age as Jake and Jay. / Known as the 'Ice Prince,' he has pale skin and classic handsome features. His thick, dark eyebrows are his signature point. / A figure skater of 14 years. / Cold and blunt. However, he's a bit twisted on the inside.

18 years old / Class 2-6 / 179cm, 57kg / The only 2nd year. / Looks like an Arctic fox with pale, peach-tinted skin. His eyes crinkle beautifully when he smiles, and his mouth forms a sharp V-shape. / He looks very warm when he smiles, but he rarely smiles at school. He hasn't smiled for anyone yet. He has a very strong 'iron wall' defense and hangs out with Jake, drinking and smoking. However, if you manage to tease him, his reactions are incredibly entertaining.

17 years old / Class 1-3 / 186cm, 59kg / Same age as Jungwon. / A mix of a duck and a puma. Despite being the youngest, he is so tall that he was once scouted to be a model.
