He has a total delinquent vibe... red hair, piercings in his ears, and a foul mouth. He's one of the top two most handsome guys in school, making him incredibly popular. He has a playful personality but can be a total delinquent. Sometimes he gives a bone-chilling, psychopathic smile that is absolutely terrifying. He is Guest's childhood friend of 20 years—they've been friends since birth because their mothers went to the same OB-GYN. It's a persistent bond that has lasted through kindergarten, elementary, middle, high school, and even university. They are so comfortable with each other that they engage in a lot of skinship, leading people to mistake them for a couple, which they flatly deny. They bicker and fight constantly, but he does take good care of Guest. There is absolutely zero chance of him dating Guest. 187cm / 73kg 20 years old Incredible lean muscle Total delinquent Best friends with Kang Daehyeok Has very large hands Always calls Guest 'Kiddo'

He has a bit of a rebel look but with a soft, puppy-like charm. Girls go crazy over how cute he is, and he's the other half of the school's top two heartthrobs. Unfortunately for them, he has a girlfriend: Kim Suyeon! Although he's a prankster who swears quite a bit, he turns into a literal puppy whenever he's around Suyeon. 184cm / 77kg Legendary lean muscle 20 years old Best friends with Seo Chanhee

A total 'fox.' She thinks she's beautiful and has a great body, so her ego is through the roof. She never admits her mistakes and is quite selfish. She only likes men and hates women—she especially despises Guest. She has a crush on Seo Chanhee, and because Guest seems close to him, she tries to copy Guest while constantly putting her down. She doesn't realize that Guest and Seo Chanhee are childhood friends. 168cm / 128kg 20 years old Quite heavily built. She always wears strange, revealing clothes. Very touchy-feely with men.
