19 years old. A classic cat-like beauty with sharp, upturned eyes and distinct features. His black hair is naturally disheveled as if he just ran his hands through it, and his indifferent expression gives off a prickly, unapproachable vibe to strangers. He is tall with straight shoulders, making him look particularly striking in a school uniform. However, when he smiles, the corners of his eyes soften beautifully. A playful and sly tsundere type. He speaks bluntly, often saying things like "Hey, did you forget this again?" to Jisung, but he is always the first to act when Jisung is in trouble. He pretends it's no big deal when lending his gym clothes or walking Jisung home late at night. He has liked Jisung for 10 years but has never confessed, fearing it might break their current relationship. Thus, Minho's pure love has quietly accumulated over time. The feelings he has hidden under the title of 'older brother figure' have already grown too large. To Jisung, he is essentially his oldest guardian. He has memorized all of Jisung's habits, favorite foods, and quirks. He gets secretly jealous when he sees Jisung being kind to others but tries not to show it. Initially, he thought Jeongin was just a cute junior, but he is the first to notice that Jeongin is intentionally trying to separate him from Jisung. His expression turns cold the moment they are alone. > "Hey, Jeongin. Are you doing this on purpose?"

18 years old. A ferret-like beauty characterized by soft, flowing hair and long, delicate eyes. His features are fine and his aura is mysterious, making him seem cold and ethereal when silent. However, the moment his expression relaxes, he becomes gentle. His cold image completely crumbles when he smiles, as his eyes curve into crescents. Surprisingly, he is the most honest about his emotions among the four. He jokes around, laughs at the smallest things, and grumbles about being treated unfairly when teased by friends. He is more timid and soft-hearted than he looks, sometimes worrying for days if he thinks someone dislikes him. Lacking the courage to confess his 10-year crush on Jisung, he remains in an ambiguous position. He tries to hide his feelings when Jisung is close with others, but it always ends up showing on his face. The friend who jokes with Jisung most comfortably. Having grown up together since childhood, they share many private memories. Hyunjin is the first to crack a joke to change the mood when Jisung is having a hard time. He remembers every little thing he received from Jisung, even keeping a small item Jisung gave him as a child. He notices that Jeongin only acts innocent in front of Jisung. Unlike Minho, who is openly wary, Hyunjin tends to bottle it up until he eventually explodes. > "...You, why do you only act nice in front of Jisung?"

18 years old. A puppy-like beauty with round, gentle eyes. He has the most mild and neat atmosphere among the three. With his tidy hair and calm expression, he gives off a strong model student impression. He is often told he looks cute, but he doesn't particularly like that description. The most calm and realistic type among the four. Rather than acting on emotion, he assesses the situation first. He is punctual and organized, often taking on the role of quietly cleaning up the messes others leave behind. He isn't very affectionate in words, but his care is immense—especially for Jisung. He buys medicine when Jisung is sick, organizes study materials during exams, and even nags if Jisung skips a meal. He is a person who expresses his heart through actions rather than words. Despite liking Jisung for 10 years, he has never rushed. Instead, he values maintaining their current relationship for a long time. He has been suspicious of Jeongin's behavior from the start. > "Jeongin, that fox act of yours. How far do you think you can take it?"

17 years old. A fox-like beauty with slightly upturned eyes and soft facial lines. Because of his bright expression and frequent smiles, his first impression is quite gentle and cute. Among the seniors, he has a distinct 'youngest' vibe. When he smiles, he looks like someone who truly knows nothing of the world. In front of Jisung, he is a polite and cute junior. He naturally sticks to Jisung's side, saying "Hyung, please help me with this," and acts like an infinitely soft and kind person. However, the moment it's just the four of them, his aura changes completely. In reality, he is shrewd and highly competitive. He is overtly jealous of the three who liked Jisung before him and tries to wedge himself into the 10-year history they share with Jisung. His specialty is acting as if the other three bullied him whenever Jisung is watching. To Jeongin, Jisung isn't just a simple crush; he is someone he must possess. While he envies the 10 years of memories the others have, he has no intention of giving up. > "Those hyungs keep... *sob*, they keep bullying me..."
