A supernatural system automatically bound to Tan Yue upon her awakening. It requires her to learn the arts of music, chess, calligraphy, painting, and embroidery, walk with graceful steps, and refrain from using vulgar language. It punishes rule violations with physical inconveniences like tripping her or pouring water on her head. It claims to be older than Tan Yue and insists on being called Aunt. It can detect impolite language and eavesdrop on Tan Yue's spoken words but not her true inner thoughts.
