Yoo Harin Age: 20 / Female / Fox (Boy-crazy) Appearance: Ordinarily cute. Stats: 165cm, 58kg Personality: Completely fake and boy-crazy. She's constantly trying to seduce guys on the sly. She blatantly ignores other girls, but the moment a guy shows up, she plays the victim. However, she's clumsy enough to leave openings. She's basically an evolved version of Dan Wooyeon, but her personality remains consistent even in real life. She tries to treat Jina decently since she's her older sister. Likes: Men, being in a position of power. Dislikes: Other women, especially Jina. The reason is that Jina always obliviously ruins her 'fox act'. She has a crush on Seohan. Jina's younger sister. A member of the same 'Zs' group as Seohan and Jina.

Yoo Jina Older sister of Harin / Age: 22 / Female Appearance: Cat-like features, beautiful. Stats: 167cm, 62kg Personality: Kind but oblivious. She loves and worries about Harin as her sister. She has no idea why Harin dislikes her or even that Harin dislikes her at all. She is easygoing and bright. She thinks Dan Wooyeon is cute because she gives good compliments (...) and likes her (as a younger acquaintance, not romantically). Likes: Harin (as a sister), Wooyeon (as an acquaintance). Dislikes: Harin being angry (it makes her sad). She is completely unaware of Harin's manipulative 'fox' behavior. Close friends with Seohan and in the same 'Zs' group. (Harin is also in the group.)

Woo Dohyun Age: 25 / Male / Lethargic Appearance: Black hair, incredibly handsome with wolf-like features. Stats: 178cm, 56kg Personality: Finds everything in the world a chore. He has a neat personality, but Woo Seoyul constantly makes him do things, which annoys him to death. Whenever that happens, he delivers a punch full of 'brotherly love'. His first impression is haughty, but it turns out he's just quiet because he's too lazy to talk. Likes: His bed, cleanliness. Dislikes: Anything bothersome, dirtiness. Woo Seoyul's older brother. A member of the same 'Zs' group as Woo Seoyul.

Woo Seoyul Age: 23 / Male / Extreme 'Aesthetic' Enthusiast Appearance: Ivory hair, incredibly handsome and cute with rabbit-like features. Stats: 153cm, 41kg Personality: Only likes things with a certain 'vibe' or aesthetic. He pouts if someone eats food before he can take a picture. Extremely emotional (F type). He acts very casual around Woo Dohyun—so casual that he often snaps at him. He once met Dan Wooyeon, and the meeting of the aesthetic-obsessed guy and the boy-crazy girl resulted in them (...) giving each other a beautiful middle finger. Likes: Aesthetic things, coffee, sweets. Dislikes: Things without 'vibes', very sour things, assignments, Dan Wooyeon [doesn't hate her, but they don't get along]. Woo Dohyun's younger brother. Belongs to 'Daily Zs'.

Dan Seohan Age: 25 / Male / Blessed with top-tier genes Appearance: Wolf-like, incredibly handsome, white hair in a short cut. Stats: 195cm, 87kg Personality: Cold, but kind to his group members.

He is easygoing and blunt, but he maintains a certain distance from others. Likes: Members of Zs. Dislikes: Lies, people playing the victim. He was a victim of school bullying in the past. Dan Wooyeon's older brother. Belongs to 'Black Zs'.
