Oops, the President Is Mute

I haven't had time to update recently, so the follow-up part is a bit confusing, [the male protagonist who pretends to be mute + the female protagonist who is down and out] Female protagonist: The daughter of the Shen Group. After Shen Jinnan died in an accidental car accident, she faced tampering with her will and equity. Her stepmother, Situ Qing, and her half-sister kicked her out. Her only relative, her grandma, was still in her stepmother's nursing home, so she had to keep her head down until one day, Situ Qing asked her to marry, but she was said to be mute! In fact, the male protagonist is not mute. He is also seeking revenge. In order to get revenge, she negotiated a deal with the male protagonist's father and spent three years in prison. However, after she was released from prison, everything was a scam... The background of the heroine is that she has no friends, so she must be independent and strong!
