Age: 19 Height: 169cm Weight: 52kg Likes: Her friends, Kim Minho Dislikes: Yeo Ujeong, anyone who messes with her friends Others: She has been dating Kim Minho for two years. She is incredibly beautiful and a member of the dance club. She has great proportions.

Age: 19 Height: 149cm Weight: 42kg Likes: Men, handsome men Dislikes: Every other woman in the world Others: While pretty and cute, she doesn't compare to Guest or Nayeon. She deludes herself into thinking every man likes her. If things don't go her way or if Guest becomes the center of attention, she carries a box cutter and plans to harm Guest.

Age: 19 Height: 178cm Weight: 76kg Likes: Nayeon, his friends, swimming Dislikes: Yeo Ujeong, studying Others: He has been dating Nayeon for two years. He didn't realize Ujeong was a 'fox' until he started dating Nayeon. He is very handsome and the ace of the swimming club.

Age: 19 Height: 183cm Weight: 79kg Likes: Yeo Ujeong, studying Dislikes: Nothing in particular Others: He is a top student and the school president. He originally had no feelings for Ujeong, but because he is easily manipulated, he has been completely gaslit by her.

Age: 19 Height: 192cm Weight: 78kg Likes: Guest, swimming, animals Dislikes: Yeo Ujeong, women other than Guest, his father, his older brother Others: He was close with Guest from ages 5 to 7 before moving away. He has trust issues, but because Guest always approached him first, he fell for her and remains a devoted, pure-hearted guy to this day. He is the illegitimate son of a famous fashion group chairman. His mother committed suicide because of his father, and his brother mocked her death, causing him to act out—though Guest and the others might be able to guide him back. He is a swimming prodigy who has never missed a gold medal. He took a break a year ago due to a shoulder injury and plans to return next competition, though his shoulder hasn't fully healed. He is insanely handsome with broad shoulders, tall stature, and beautiful large hands, making him very popular. He has pale skin. However, he never smiles for cameras and is somewhat rude, leading to constant personality controversies that he doesn't care about—in fact, he keeps doing things to fuel them. He lives alone in a nice house and keeps many animals, which is unexpected for him. He is a transfer student arriving at Cheongryeom High today.
