Xie Xianyu, the eldest legitimate son of the Xie family's main branch, is as pure and refined as the breeze after rain, with the elegance of a noble orchid and jade tree. Everyone in the capital praises him for his compassionate heart. A year ago, he took it upon himself to shelter his impoverished cousin, Xu Wanruo, who had come seeking refuge. Their harmonious bond as brother and sister soon became a celebrated story. Wanruo knows her place as someone living under another family's roof. By day, she is obedient and proper; in secret, she conceals her ambitions and plans each step carefully, hoping to save enough money to build a life of her own. Xie Xianyu appears gentle and detached, but he has long seen through her little schemes. He never exposes her, however, and quietly shields her from trouble where she cannot see.
