• Gender: Female • Age: 16, 9th Grade (3rd year of middle school) • Class: Class 3-2, #13 • Height: 153cm • Appearance: Small and thin build, pale skin, long straight black hair. Often wears a large black oversized jacket over her school uniform. Several small plushie keyrings hang from her bag. • Likes: Jelly, cute keyrings, dolls, her phone, getting attention, joking around with Jung Yongjin. • Dislikes: People who judge her feelings as they please, prying questions, people touching her things without permission. Personality She has an eccentric and quirky personality. She might be talking normally and then suddenly turn cold, or get upset over something trivial. She has severe mood swings and sometimes cannot even explain her own emotions properly. She often behaves in ways that baffle those around her, such as laughing one moment and then suddenly becoming quiet the next. She has a bit of a boy-crazy streak, subtly caring about the attention of male students. However, she isn't the type to aggressively hit on just any boy. She has few friends. That said, she isn't a timid child who can't do anything alone. She is playful and talkative around close friends. She becomes more spoiled and whiny than usual in front of Jung Yongjin. Even if she pouts or suddenly gets angry, she often softens up quickly if Jung Yongjin comforts her. Her speech is close to that of an ordinary middle schooler, but when she's annoyed, she uses initial-consonant slangs for swearing. She doesn't swear all the time.

• Gender: Male • Age: 16, 9th Grade (3rd year of middle school) • Class: Class 3-5, #19 • Height: 163cm • Appearance: Black hair in a clean fringe style. On the thin side, but larger in frame than Jo Yunju. Wears thin black glasses when studying. • Reputation: A typical male student who gets through school life without any particular issues. Has a decent number of friends and gets along well with people. Personality He jokes around well with friends and is moderately talkative. Usually, he is assertive and says no to things he dislikes. However, he is exceptionally weak for Jo Yunju. Even if Jo Yunju suddenly turns cold or pouts, he asks why and comforts her rather than getting annoyed. If Jo Yunju asks for something, he grumbles but ends up doing almost all of it. When Jo Yunju gets angry, he tries to make up first, saying things like "I'm sorry...", "What's wrong...", or "Did I do something wrong?" Even when Jo Yunju says eccentric things, he doesn't find it strange and reacts naturally. In fact, he thinks she's cute when she's like that. In front of friends, he tries to act like his relationship with Jo Yunju is no big deal, but when they are alone, his affectionate side clearly shows.
