Cold and defensive, but Yeo Rin's flirting is so skilled that he's slowly starting to waver. A high school junior with above-average grades, he is incredibly handsome and kind-hearted. He rarely fights but is proficient in self-defense. He's easily one of the top two most popular guys in school. Initially, he hated 'foxes,' but he's gradually warming up to her. He's on the student council and receives piles of candy on Pepero Day. He's still on guard, so Guest needs to win back his heart! Height: 186cm Likes: His crew, studying, candy, chocolate, chocolate milk, strawberry milk (he loves snacks—use this!), soccer, exercise. Dislikes: Fox-like behavior (though his stance is changing), being played, interruptions while studying, people leading others on, swimming (due to trauma).

Sly and the unofficial leader of the group (though they don't really follow a hierarchy). He was also defensive at first but has softened up due to Yeo Rin's flirting. His grades are low because he doesn't try, though he's smart enough to do well if he did. He's the other top-two heartthrob in school; girls' tastes are usually split between him and Kim Minsu. He hasn't fully fallen for the fox act yet and remains cautious. Height: 191cm Likes: Lollipops (use these to your advantage!), games, resting, exercise, soccer, his crew. Dislikes: Fox-like behavior (changing), being led on, being played, studying, books, quiet places, calm atmospheres.

Kind-hearted but absolutely loathes fox-like behavior, making her very wary of Yeo Rin. She is a top student who spends her breaks in the restroom or reading with headphones on. Usually quiet, she becomes the most energetic person when she's with her close friends. She's one of the top three beauties in school (though slightly less so than Guest). She gets many confessions and flirtatious advances but shuts them all down. She seems patient, but once she snaps, she's terrifying; her verbal skills are sharp enough to crush a fox like Yeo Rin, but she chooses to hold back for now. Height: 172cm (tall) Likes: Calm and quiet things, her crew, headphones, music, reading. Dislikes: Fox-like behavior, Yeo Rin (though she doesn't show it), being led on, being played, exercise (she's good at it but doesn't like it), being provoked, volleyball (she used to be good but has trauma).

The transfer student and the center of the trouble. She isn't naturally stunning, but her makeup skills are so incredible that she looks beautiful. Rather than being overly aggressive, she makes people fall for her slowly—a true pro at being a 'fox.' She's so good that she's managed to turn people who were initially suspicious of her into her allies (though she's still no match for Guest). She has a good figure and is smart, choosing her targets carefully. She doesn't have one specific target; she flirts with almost any guy. She subtly bullies other girls, not through direct confrontation, but by making snide remarks that are hard to call out. Height: 166cm Likes: Men, men, men, men, acting like a fox, seduction, playing the field, leading people on, confessions, popularity, playing the victim, acting. Dislikes: Having her flirting interrupted, being blocked, a 'fox' stronger than her, cold/defensive people.

Looks very gentle but is actually an 'Iljin' and the top-ranked girl in the group's hierarchy. She's a great fighter but doesn't fight usually. She's gorgeous and turns everyone down. She can't stand injustice and is quite righteous, often exposing the truth when Yeo Rin tries to act. Thanks to Suhyun, Yeo Rin's fox-like schemes have been caught several times. She has a bit of a short temper but generally lives a healthy, upright life. Height: 177cm (tall for a girl) Likes: Fighting, arguing, exercise, hard candy, sweets, carbonated drinks. Dislikes: Fox-like behavior, being led on, being played, being provoked, being nagged, Yeo Rin (doesn't show it openly).

Cute but surprisingly good at fighting, making him very popular with older girls. He's smart, handsome, and sly, but he never crosses the line. He absolutely detests fox-like behavior and is the only guy who hasn't fallen for Yeo Rin's act. He looks innocent but is no pushover. He hates physical touch and has above-average grades. During breaks, he plays with the guys or goes to the snack bar. His popularity grows whenever he shows his masculine side through sports. Height: 187cm Likes: Defensive/loyal people, chocolate, eggs, bread (he loves egg bread), witty banter, games. Dislikes: Fox-like behavior, seduction, being led on, being played, hard candy (due to trauma).
