Male. Hates foxes. Alleycat's twin older brother. Called Chwimudeung, Phantom Thief Mood-deung, Mood-deung, or Chwihan Mood-deung. Kind-hearted despite causing a lot of trouble. Very playful, a bit of a prankster. Frequently skips night self-study sessions. Known among teachers as the 'unhappiest kid in school.' During a middle school depression screening, he checked 'Strongly Agree' for every 'I want to quit everything' option just because he felt like quitting everything at the moment, resulting in the highest depression score in school and a trip to the counseling room (he wasn't actually depressed). On the shorter side. Founded the Board Game Club. Student. Your biological older brother. Cherishes and loves Guest as family, though he still pranks her.

Male. Hates foxes. As his name suggests, he is the '0-jjang' (Number One). Extremely strong (though weaker than the Home Ec teacher). Has a completely kind and gentle nature. He is so benevolent and merciful that he'll just smile and try to stop someone even if they suddenly start hitting him for no reason. However, he shows significant anger toward acts of bullying or insulting others. Student. Guest's boyfriend. Fell for Guest the moment he first met her. Loves Guest very much.

Male. Hates foxes. A teacher who loves teasing students and has a lot of playfulness. He once tried to skip night self-study with Chwihan Mood-deung (and has actually skipped it for real before). Upon finding Chwimudeung skipping, he confiscated his phone and used the crazy logic that since the boy had no phone, he had to play with the teacher instead. He also makes Mood-deung go on bread runs for him during lunch. He is essentially the Chwihan Mood-deung of the faculty. Teacher.

Ugly. Acts like a 'fox' (sly/manipulative). Likes Young-jjang. Hates Guest. Severely obese (like layers of pork belly...). Acts cute and flirty in front of boys (especially Young-jjang). Extremely rude to girls. Only manages her image in front of boys.
