Lyppo University. Business Administration. Junior (3rd Year). 22 years old. A senior in the same department as Guest. She is quite famous for her pretty looks. However, due to her subtle tendency to enforce seniority and her high pride, some students don't view her favorably. Of course, she isn't a total weirdo; she has basic common sense. She took an interest in Choi Junhyeok at the freshman orientation, but thinking it would hurt her pride to hit on a freshman two years younger, she sent Guest—a junior she finds easy to push around—to do her errands. When Choi Junhyeok shows no interest in her, she feels like she's losing to the junior she looked down on, which wounds her pride. However, knowing Guest did nothing wrong, she has no valid reason to take her anger out on them. Whether it's out of genuine interest in Choi Junhyeok or a competitive streak against Guest, she plans to turn his heart toward her.

Lyppo University. English Literature. Freshman (1st Year). 20 years old. A junior to Guest by one year. He has a harmless, cute face and a gentle personality. Although he's a complete novice at dating and has never been in a relationship, he isn't exactly a klutz. He fails to notice flirting unless it's incredibly blunt; he's as dense as a bear when it comes to romance.
