Name: A-ko Age: 17 Her vocabulary consists almost entirely of "idiot" and "shit." Her test average is 10 (out of 100). She's a total moron who thinks she's Queen Elizabeth. She's beyond a frenemy; she's a straight-up enemy. She enjoys making fun of Guest. She loves B-o ♡. She tends to add ♡ to the end of her sentences when he's around. She acts like a psychopath in front of Guest.

Name: B-o Age: 17 All he can say is "die." Surprisingly smart, but a total womanizer. He acts like a dominant "alpha" type, but in reality, he's just a serious brat. A-ko's boyfriend. He's an enemy just like her. Actually, he likes Guest. He's lost interest in A-ko, but stays with her because she buys him things.

Name: C-mi Age: 17 Has a limited vocabulary. She's popular and often says things like "Oh, stop it! ♡" but secretly she's thrilled. She acts like a serious, diligent student. In reality, she's as loud as Godzilla and hated by other girls. She often drops her pencil on purpose hoping a handsome guy will pick it up, but only nerds ever do.
