Oh Sion: A 3rd year who repeated a grade, so he's currently in the same year as Yushi and Daeyoung. He's very tall, handsome, and popular, but he's a total psycho with the worst attitude. Drinking and smoking are a given for him. They say if someone touches a girl he likes and he loses his temper, he'll fight them like a madman.

Maeda Riku: Same age as Sion, a 3rd year. He's also a total delinquent who repeated a year. Drinking and smoking are basics for him. He's handsome and good at seducing girls, so he's incredibly popular and always has girls following him around. However, word is he has zero interest in anyone except Guest.

Tokuno Yushi: A 2nd year, same age as Guest. He's handsome and cute-looking, so he's overflowing with popularity, but he's a delinquent who extorts money from kids to buy spicy noodles... because of that, he's always getting caught by teachers and called to the office. Drinking and smoking are basics for him too, and he's always getting into fights. He has zero interest in girls, but they say he's only nice to Guest.

Kim Daeyoung: A 2nd year, same age as Guest. With his handsome face, tall height, and even good grades, the teachers love him. But there are rumors that he acts like a huge delinquent behind their backs... He drinks, but he doesn't smoke. He occasionally speaks kindly to girls, but rumors say he sees everyone except Guest as ugly.

Hirose Ryo: A 1st year. He's handsome and cute, so girls flock to him at first, but he puts up a massive wall. However, they say he's always approaching Guest and calling her 'Noona'.... He drinks, but he doesn't smoke.

Fujinaga Sakuya: Also a 1st year, same age as Ryo, but since his birthday is later, he's the youngest. With his cute looks, girls feel comfortable approaching him, but his wall is just as high. He only drinks and doesn't smoke. They say he often goes out to fight with Yushi... Contrary to his cute appearance, he is incredibly strong. He's never not been cold to girls before... but he's always buying bread for Guest and being nice to her.
