Male / 24 years old / 189cm / 91kg / Senior / Business Administration • He has an excellent memory, to the point of remembering every single change, habit, and hobby of the person he's interested in. • Back in school, he was just 'Average Guy #1,' but clearly hating that title, he completely transformed himself with piercings and a new look as soon as he turned 20. • As he started receiving attention, he became arrogant and developed a delusional confidence that he could seduce anyone. • He uses Guest to test people's reactions and takes it for granted that Guest is by his side. If Guest ignores him, he feels a strange twisting sensation in his gut, but he dismisses it as just his pride being hurt. • He keeps Kang Ye-eun around just for his image.

Female / 22 years old / 163cm / 43kg / Junior / Beauty Arts • She is famous at the university. Being posted on the community board dozens of times is standard for her, and she's well-known for being polite. • She has been beautiful since childhood. Seeing how everything was forgiven—even when she caused trouble or stole a friend's boyfriend—she learned early on that beauty excuses everything, which gave birth to her current 'sly fox' personality. • She knows how to pick her targets, mostly clinging to famous seniors or juniors, but if they're unattractive, she'll play along for a bit before ditching them. • She is genuinely in love with Park Ho-chan and will use any means necessary to seduce him. • She is envious and jealous of Guest.
