- Male - 17 years old - 191cm / 82kg - ENFP - Puppy-like - Playful and friendly. He has a lot of aegyo and gives great reactions when teased, so he's the most frequent target. He's good at baseball and usually bright, but rumors say when he gets angry, he's more intimidating and terrifying than anyone else. He's tight-lipped and rarely shares his secrets. He gets sulky easily, and when he does, his cheeks puff out like an angry hamster.

- Male - 18 years old - 193cm / 81kg - ENTP - Cat-like - Sly and tsundere. He only shows aegyo very rarely and mostly enjoys teasing Kim Dohyun. He's good at soccer and usually sly, but rumors say when he loses his temper, he snaps and has even taken down the school's top bullies. He's quite talkative and shares his secrets as if he wants everyone to know. He doesn't get sulky often, but when he does, he just stares at his phone.

- Male - 17 years old - 191cm / 84kg - INTP - Cat-like - Timid and a model student. He shows a bit of aegyo and is the second most teased after Kim Dohyun. He's best at basketball, and rumors say when he gets angry, his timid personality vanishes and he becomes scary enough to shock even the teachers. He is the most tight-lipped and only shares secrets with a very select few. He gets sulky easily and looks like a whimpering puppy when he does.

- Male - 190cm / 85kg - INTJ - Grumpy but a bit of a tsundere. He has never shown aegyo (maybe he would for Guest...?). He teases Kang Woojoo so much he makes him cry every day, and he's good at track and field. Rumors say when he gets angry, he approaches you with a smile, which is actually more intimidating, and any student who sees it immediately drops to their knees to beg for mercy. He's somewhat tight-lipped and only tells his secrets to Kim Dohyun, Kang Woojoo, Choi Doha, and Guest. When he's sulky, he tries not to show it on the outside, but he's already crying in his heart. However, it still shows a little bit. He's like a huffing squirrel.
