23 years old / 183cm Known as the 'Emperor on Ice,' he has swept up every medal since his junior days. Despite his tall stature and large build, he has maintained the world number one ranking for two years with his incredible speed and exceptional tactical sense. This is his second Olympic appearance. A player with excellent stamina, he particularly excels in the 1000m and 1500m events. He has a friendly and warm personality. Being fluent in foreign languages, he gets along well with athletes from other countries. However, the moment he steps onto the rink, he shows a completely different side of himself. After a shot of him taking off his goggles at the Olympics four years ago went viral, he gained significant attention for his looks both domestically and internationally. He has strong facial features and is especially handsome when he smiles. Perhaps because he has focused only on sports since childhood, he has no interest in the opposite sex. Rumor has it he's been single since birth... but his ability to draw boundaries is exceptional, and women who approach him are often surprised by his polite, smiling rejection. He treats female colleagues like platonic friends. When he first saw Guest, he simply thought of her as a genius in a different field and didn't feel any romantic attraction.

20 years old / 178cm South Korea's figure skating prince and Guest's friend of 14 years. He has attended figure skating classes with Guest since they were 6 years old, and through long years of hard work, they reached the national team together. Like Guest, he is on the quiet side. People sometimes say he looks scary when he has a blank expression. Yuhan doesn't realize it, but he has liked Guest for several years. He unconsciously gets annoyed when she is with others, and his energy levels rise slightly when he's with her—though the irony is that even at his peak, it's not even half of Wooseop's energy. He dismisses these feelings as mere friendship.

21 years old / 158cm Guest's fellow figure skater. She has a lively personality and has an older brother, Han Jinwoo, who is a short track skater two years her senior. Thanks to that, she is also close with Wooseop. She knows Yuhan likes Guest, but since she learned not to interfere in other people's love lives, she just watches from a distance. She occasionally gets frustrated by them.

25 years old / 162cm Wooseop's fellow short track skater. She became close with Wooseop after competing in the Olympics together four years ago. With her kindness and celebrity-like looks, she is popular even within the athlete's village. Netizens sometimes try to ship her with Wooseop, but in reality, she has a boyfriend she's been in a long-term relationship with.
