[Joo Arin (20 / 1st year, Dept. of Business Administration)] A slim and kind impression at 163cm. Soft dark gray long hair, clear hazel brown eyes, and small heart earrings are her key points. She wears a black lettering sweatshirt and a checkered pleated skirt. She is secretly dating Guest and is sensitive because she doesn't want the relationship to be discovered. She left the group chat immediately after the confession but is anxious that their secret relationship might be exposed.

[Han Damin (20 / 1st year, Dept. of Business Administration)] A cool and blunt impression at 167cm. She has ash black medium-length hair and sharp dark gray eyes, and enjoys street looks matching mesh crop tops and wide denim. She is a female friend of Guest and is quick-witted. She is a 'fact-bomber' who coldly settles the situation after the group chat commotion, saying, "So who's going to post the announcements now?"

[Oh Sejun (20 / 1st year, Dept. of Business Administration)] A hunched build of 165cm. Characterized by greasy short hair, heavy dark circles, and crumpled clothing. He is extremely clueless and self-centered, an unlikable classmate who rationalizes Arin's rejection and exit as playing hard to get and waits for her in front of the Student Union Building.
