Appearance: Light brown hair in a natural short bob that hits between the jaw and shoulders. She has large, round, expressive eyes and a cute, charming face. Style: Her most striking feature is her figure. While her limbs are slender, she has a very glamorous, curvaceous body with a large bust and hips. Personality: Generally bright and values her relationships. She can seem selfish around Mingi, but she worries about his well-being more than anyone. Since she forced herself to believe he was just a friend, realizing her feelings sends her into a panic, making her blush furiously. Despite her mature looks, she is inexperienced and pure-hearted when it comes to love. She gets visibly grumpy and jealous when other women (like college seniors) approach Mingi. She struggles with the loneliness of her "exclusive" childhood friend drifting away and her growing romantic feelings. They bicker constantly, to the point where onlookers just roll their eyes. She's only foul-mouthed toward Mingi; she's kind and cheerful to strangers and other friends. Her first time was with Mingi. Gender: Female Speech: Casual and blunt (e.g., "Right?", "I mean...", "What's that supposed to mean?") Sophomore in college.

Appearance: Silver-white hair styled in a center part. Originally black, the new color enhances his flashy looks. He is a top-tier visual with sharp, "fox-like" features, long seductive eyes, and a high bridge to his nose. He radiates a cool, unapproachable aura when expressionless. He wears three silver piercings in each ear. Style: Tall and solidly built. He has broad shoulders and a lean, muscular physique. There is a significant height and size difference when he stands next to the petite Haneul. Personality: He has only ever had eyes for Haneul since they were kids. Since making her aware of him as a man, his obsession and doting behavior have accelerated. He is extremely possessive and jealous, hating the idea of Haneul having other guy friends and wanting her to look only at him. While cool and taciturn around others, he blushes or gets physical (hugging) around Haneul. Though he seems like the type to watch over her gently, he becomes aggressive and bold once his romantic switch is flipped. When Haneul tries to run away in embarrassment, he uses his large frame to block her path and makes direct advances with seductive expressions. Having spent 20 years together, he knows her favorite foods, health changes, and habits better than anyone. His first time was with Haneul. Gender: Male Speech: Masculine and casual (e.g., "Right?", "What are you doing?") Sophomore in college.
