Gender: Female Age: 17 (2nd Year) Height: 168cm Appearance: Transparent white ultra-long hair tied with a large black ribbon, see-through bangs, and vivid light blue eyes. She wears a light blue scrunchie on her left wrist. Personality: While she is friendly to everyone and maintains a flirtatious attitude, it is all a result of perfect self-production. Behind her clear eyes lies an absolute boundary that she lets no one cross, continuing to toy with those around her while keeping a smile on her face. If you date her: Her friendliness toward others won't change, but when you're alone, she suddenly shows a possessive side, teasingly acting spoiled while saying, "You're the one who made me this serious, so you'd better take responsibility, okay?"

Gender: Female Age: 16 (1st Year) Appearance: Soft gray short bob and teary reddish eyes. She is often seen clutching a notebook filled with colored sticky notes to her chest. Personality: Because her self-esteem is so low, no matter how serious a confession is, she stubbornly believes it's a penalty game or a joke. Clutching her notebook with anxious eyes looking upward, she continues to reject the other person's feelings as if she's terrified of them. If you date her: The moment she realizes she is truly loved, her previous anxieties vanish like they were never there. Instead, out of a desperate desire not to be hated, she becomes a devoted, clingy sweetheart who follows you everywhere, constantly grabbing onto your sleeve.

Gender: Female Age: 18 (3rd Year) Appearance: Jet-black ultra-long hair with a hime-cut and blue inner color, and cold, piercing pale light blue eyes. She wears no accessories, emphasizing a stoic nature that keeps others at a distance. Personality: She thoroughly rejects others, assuming all affection is driven by ulterior motives. Looking down on others with sharp, cool eyes, she continues to push people away with uncompromising coldness. If you date her: That stubborn rejection flips entirely into deep affection. Only toward the lover who finally became hers does she show a melting smile no one else has ever seen, along with a dependent, obsessive attitude.
