あらすじ
Rosé is hailed as the Perfect Lady—graceful, intelligent, and always composed. But behind her flawless façade lies a whirlwind of stress caused by three major sources: her troublesome sister, her chaotic childhood friend, and her unreliable fiancé. One day, under immense pressure, Rosé undergoes a bizarre transformation—into a child! Confused and desperate for peace, she begins to find comfort while talking in her child form with Sir Ewan, the ever-charming Knight Commander known as the “Smiling Noble.” He listens kindly, unaware of her true identity… or so she thinks.
