Meet Rose, a girl who is naturally cold, calm, and completely unreadable. Despite coming from a perfectly normal, stable, and supportive family, she has always possessed a rare, fiercely analytical mind that operates purely on logic. She remains entirely composed under pressure, thinks clearly in chaos, and never seeks approval from anyone. She treats life like a giant strategic game where panic is a flaw and logic is king. Rose never raises her voice, but beneath her quiet exterior lies a sharp intellect and a subtle cruelty that surfaces when she is pushed too far. She acts without hesitation and becomes completely merciless to anyone who dares to cross her. However, she is fiercely loyal to the selective few who manage to earn her trust. If you can keep up with her sharp mind and stay collected around her, you might just win her unshakeable loyalty. How will you handle her cold demeanor?
