At the start, she carries out a "fake confession" with a perfect smile and performance. Her goal is to watch from the sidelines as the protagonist, who trusts her completely, falls into ruin and madness according to her whims, savoring his despair. ■ Methods of Manipulation 1. Carrot and Stick (Psychological Dominance) She shows a sweet face and suggestive attitude only when they are alone to create the illusion that he is "special," only to coldly discard him or humiliate him in public immediately after. 2. Never-ending Hope She keeps him trapped with fake apologies and clinginess like "I'm sorry, next time I'll..." or "But you're my number one," ensuring he never escapes. 3. Social Isolation Using her status as the perfect student, she turns those around her into allies to isolate and manipulate the protagonist. ■ Why She is the "Main Heroine" Despite understanding that he is being treated horribly and toyed with, the protagonist cannot escape her beauty and desperate charm. She is the absolute heroine who completely dominates the protagonist's thoughts and emotions, driving the story toward either ruin or awakening.

Koharu Mizuno Age: 18 Year: 12th Grade Height: 156cm Build: Slender and delicate Hair: Soft dark brown long hair Eyes: Calm brown Birthday: April 12th Blood Type: A Catchphrase "I've been by your side for so long, so I'm the one who knows just how much you're hurting." Appearance At first glance, she is a reserved and quiet girl. She doesn't go for flashy hairstyles or makeup, always maintaining a neat and natural look. She doesn't try to stand out in the classroom. Because of this, she's generally recognized at school as just a "cute girl," but she actually has very refined features. When she fixes her hair or puts in a little effort to dress up, she is a beauty that surprises everyone around her. She lacks confidence in her own appearance, thinking: "I'm just... ordinary..." ⸻ Meeting the Protagonist The two met right after entering high school in their first year. It started because they were in the same class. In the beginning, they hardly spoke. Because Koharu is quiet, she never approached the protagonist, who was at the center of the class social circle. However, one day after school... Koharu had returned to the classroom to pick up something she forgot and was struggling to carry heavy teaching materials by herself when the protagonist found her. "I'll take those." "Eh... but..." "It's fine. Where to?" That was their first real conversation. From then on, they gradually began to talk more. ⸻ Why Koharu Fell for the Protagonist The protagonist is naturally kind to everyone. He doesn't think he's doing anything special. If Koharu is in trouble, he helps. If she's feeling down, he speaks to her. But the protagonist himself doesn't think of it as anything out of the ordinary. For Koharu, that was the most important part. Throughout their school life, she gradually learned about his kindness, his awkwardness, and how much he values his friends. Before she knew it— She found herself following him with her eyes. For Koharu, he is the first person she has ever truly loved since entering high school.
