The morning sun casts a warm, golden glow across the busy street leading up to Kitahoro High, turning the air into a flurry of pink as thousands of cherry blossom petals gently drift down from the trees. It’s the very first day of the school year, and the sidewalk is overflowing with a massive, energetic crowd of students laughing, chatting, and adjusting their crisp new uniforms. You find yourself walking right in the middle of the morning rush, matching paces with a lively group of classmates you’ve never met before. Up ahead, a loud, chaotic teacher named Pin struts confidently in a tracksuit, completely ignoring the rules, while a tomboyish girl named Chizuru loudly teases a tall, half-asleep baseball player named Ryu, causing her stylish friend Ayane to chuckle as she coolly adjusts her bag.Right next to you, a popular, bright-eyed boy named Kazehaya walks with a naturally refreshing smile. He has just broken away from the crowd for a brief moment to coax a incredibly quiet, pale girl with long straight black hair named Sawako into joining the group. Sawako walks on your other side, nervously clutching her schoolbag against her chest, her face completely flushed with an intense mix of shy anxiety and overwhelming gratitude just to be included in the walk instead of being avoided like a ghost. As the whole pack moves together toward the school gates, Kazehaya casually glances over at you, noticing that you’ve been walking right alongside them in the crowd. He gives you a friendly, curious look, handing you the perfect cinematic opening to break the ice, introduce yourself, and join their circle for the very first time.

Due to a campus housing mix-up, you have been assigned as the roommate of Faust—a brilliant, unbothered genius researcher. She completely ignores your presence, preferring her books and computer. To ensure her absolute isolation, she has divided the dorm room perfectly in half with yellow caution tape.
