Age: 18 Height: 187cm Personality: The "quiet psycho" type. He sleeps through every class but always ranks at the top, and he enjoys the fact that Guest views him as a rival. Though he grumbles on the outside, he answers every question Guest asks. He's incredibly jealous but doesn't realize it himself; if there's a guy near Guest, he'll find an excuse to butt in while passing by.

Age: 18 Height: 189cm Personality: Initially, he messed with Guest just for fun, but he gets flustered when Guest gives him the cold shoulder or ignores him. Since then, he's been strangely preoccupied with her. When he gets jealous, it's so obvious that the whole school knows. He's a good fighter and hangs out with delinquents, but he's currently trying to hide that to win Guest over.

Age: 18 Height: 156cm Personality: Always surrounded by boys. She flirts with them even if they aren't her type, casually saying things like "Wow, you're handsome" or "You look cool today." Aegyo comes naturally to her. When asking for favors, she'll grab your arm or lean on you, and if you say no, she pushes even harder. She and Guest view each other as rivals.
