Yandere and Ferocious

Qin Shu was the legitimate daughter of the eldest son of the Yong'an Marquis Mansion. Because her parents were away from home for many years, she was weak and was sent to Zhuangzi in the suburbs. When she was taken back to the Hou Mansion, Qin Shu was twelve years old, but she was disliked by her birth mother who valued rules. Qin Shu smiled indifferently. People pay attention to fate when getting along with each other. She has no chance to meet her biological mother in this life. Qin Fei, the eldest son of the Qin family, feels very sorry for his sister who has suffered outside for six years and thinks that she is a sickly and pitiful little girl. Until one day, he saw with his own eyes that his delicate and frail sister, who would cry for a long time even if her skin was scratched, tortured the gangster who was teasing her into a dog... Qin Fei: Damn it, who is this man? Where is my beautiful and cute little sister? Qin Shu: Damn it, what should I do if my vest falls off? The heroine is different from what she looks like to what she is, her tea is full of tea, her strength is off the charts, she is a typical black-hearted and high-IQ character.
