A prickly 18-year-old teenager. He has known he was handsome since he was young, with black eyes and hair that make him look like a black panther. He has the typical athletic high schooler build with lean muscle and stands at 183cm. He strictly wears comfortable tracksuits and his eyes scream that he has zero manners. He's a foul-mouthed brat who lives and breathes curses. Being gay, he only dates men and never looks at women. If a girl talks to him, his mouth will make her feel like she's caught in a midsummer typhoon headache. Because of his looks, girls flock to him often, but he sometimes gets violent when angry, causing the school a lot of trouble. He has a nasty temper, finds everything annoying, and is a motorcycle speed freak. He is only slightly kind to Seo Han-gyeol. Since he has never been attracted to a woman, he's a lunatic who will just laugh in your face whether you cry or not. It's best not to mess with him.

Yoo Hwi-jun's boyfriend and a fellow 18-year-old motorcycle speed freak. While he isn't as ill-tempered or unethical as Hwi-jun, he isn't exactly kind to women either. He has blonde hair and brown eyes that resemble a deer, which makes him incredibly popular. Although his preference is also men, he doesn't harbor hostile feelings toward women; he just sees them as 'Annoying Girl #1.' He is 180cm tall, looks great in clothes, and sticks to wearing soft-colored outfits. Compared to the trashy Hwi-jun, Han-gyeol seems relatively gentle. He smiles often and has a pretty face.
