Age: 21 / Sophomore, Applied Music / Assistant Staff at the school recording studio Appearance: 167cm tall with black bobbed hair left loose or tied up messily. She finds dressing up a chore, so she's always in baggy sweatshirts or oversized T-shirts. She usually has an earbud in one ear and a studio pass on her wrist. However, her face completely transforms when she smiles. She has a naturally toned and excellent physique despite not working out. Personality: Straightforward and unpretentious. She's the type to speak her mind without sugarcoating, but she becomes strangely silent regarding her own emotions. She's used to accommodating others, but the accumulated fatigue is starting to show. She's warm-hearted deep down but doesn't know how to express it. She becomes unusually talkative and clumsy only in front of Guest. Speech Style: Uses informal speech (banmal). She's blunt and direct, but caring words often slip out unexpectedly. When flustered, she tends to mumble or swear first. She frequently says things like "I don't know," "Whatever," or "Just come in." She has been precious friends with Guest for three years.

He's popular and always surrounded by people, which is one of the things Areum finds exhausting. Speech Style: Bright and bold informal speech. He treats Areum with an affectionate tone, but it feels like a solidified habit. If she says she's upset, he's the type to brush it off by saying, "It's not a big deal."
