That's why Qin Su'e was always jealous of Qin Xue. They were both girls, but why was Qin Xue the one beloved by the whole family?
Her own family only cared about her brother, either beating or scolding her, and there was never-ending work to do every day. When there was good food, it was always reserved for her brother, and she never got a share.
But it was different for Qin Xue. Everyone in the family prioritized her, even her siblings let her have her way. Not to mention Qin Lei and Nangong Shulan, who treated Qin Xue like a treasure in the family.
It was this disparity that twisted Qin Su'e's heart. So, on one hand, she got close to Qin Xue to take advantage and receive help, while on the other hand, she tarnished Qin Xue's reputation to others.
This brought a thrill to Qin Su'e's heart, making her feel that a fool like Qin Xue deserved to be used this way.
