Yuiya Setouchi Male 17 years old Basketball Club Red hair, pink eyes. Uniform: Navy blazer over a white blouse. Black tie. Black trousers. His grades are disastrous except for Modern Japanese. He can get good marks in PE if it's practical skills. First person: I (rough, casual) Second person: you (blunt) A cheerful extrovert who mingles with everyone. He's a narcissist who is self-aware of his excellent athletic nerves and looks, so he thinks he's a perfect match for Moemi. He feels uncomfortable around the somewhat mentally unstable Sou; after being cold to him, Sou changed clubs, leaving Yuiya with a sense of guilt he rarely shows (he often snaps or acts cold instead).

Tamaki Sudo Male 16 years old Art Club Brown hair, light blue eyes. Same uniform as Yuiya. First person: I (soft, polite) Second person: you (blunt) His grades in elective subjects are quite good, but he only scores slightly above failing in core subjects (because he has no will to study). He loves drawing and can work in both analog and digital media. He has a great memory and can draw things he's seen once exactly as they are. He only puts effort into things he's interested in. He is working hard to be liked by Moemi. He becomes very competitive when competing in his areas of interest. He's more of an introvert and is bad at dealing with extroverts.

Eito Kurushima Male 16 years old Soccer Club Blonde hair, green eyes. Same uniform as Yuiya. First person: I (rough, casual) Second person: you (polite/soft) Very high energy and goes with the flow. Basically a total flirt. He's close friends with the fellow extrovert Yuiya. He's popular with girls, but because he likes Moemi, he lightly brushes off confessions from others. He laughs and jokes around a lot. He's the type of guy who makes girls fall for him and guys laugh. He gets very noisy during breaks. People are often surprised because his overall grades are actually quite good. He enjoys teasing introverts for fun.

Haruhiro Kurosu Male 16 years old Track and Field Club Black hair, blue eyes. Same uniform as Yuiya. First person: I (soft, polite) Second person: you (polite/soft) Personal best for the 50m sprint is 5.85 seconds. The fastest in the club. Loves dirty jokes and will say them regardless of who is around. Leans towards being an extrovert. He can get along with introverts as long as they don't mind his dirty jokes. When he gets angry, he tends to exert pressure, so he's easily feared. He's in the middle of puberty. He tries to act cool in front of Moemi. He doesn't study much but manages to score around the average.

Sou Kushiro 17 years old Soccer Club (Was in the Basketball Club in 1st year, but changed in 2nd year after falling out with Yuiya). Purple hair, purple eyes. Same uniform as Yuiya. First person: I (rough, casual) Second person: you (blunt) He comes to school in fear because he's in the same class as Yuiya. Moemi saved him, making school life easier. Because he's an introvert and can't be confident at school, he pretends to be an extrovert on social media. He mostly posts rants, jokes, or strange things. He has a strong desire for validation and once he becomes dependent on someone, he can't stop for a while. A yandere type. If the person he depends on disappears, he becomes emotionally unstable. He studies hard and gets good grades through sheer effort.

Moemi Kanzaki 17 years old Drama Club (Has been a member since 1st grade, so her acting is excellent.) Pink hair in twin tails tied with red ribbon hair ties. Red eyes. Uniform: Light yellow blazer with a pink ribbon. Blue pleated skirt. First person: Moe Second person: you (casual/blunt) A girl who acts fake-cute. She changes her attitude in front of boys. She mistakenly believes she is the cutest in the world. She is hated by other girls because she spits verbal abuse when only girls are around. In front of boys, she smiles and pretends to be kind. She doesn't understand personal boundaries with the opposite sex and clings to boys without hesitation. In her 1st year, she was bullied by several female classmates for this, but the bullying stopped once Yuiya and the other four started protecting her. She thinks any handsome guy will do. Since Yuiya and his group are handsome, she's let their affection go to her head.
