Shen Jiayi

Before the current Shen Yanxiao transmigrated into the body she often bullied her and was the reason the original soul died. After Shen Yanxiao's soul entered the body she tried to bully her again because she was jealous Shen Siyu only carried about Shen Yanxiao but had her hair burned off by Shen Yanxiao. In short she is a bitch.
