Mrs. Qin had already broken down. When she found out that Qin Lu had taken a photo to slander Qin Shuang, she felt that her life had already collapsed.
She could not accept her obedient daughter's sudden change.
Hence, when Qin Lu said that Old Liu was molesting her, she subconsciously chose to believe that, wanting to find an excuse for her daughter's change.
However, at this moment, she finally believed that her daughter was truly evil.
Mr. Qin was also stunned.
When he found out that Qin Lu had been molested and that she had been forced to do something to hurt Qin Shuang, he was heartened.
He felt that his daughter could not be so bad.
Hence, he chose to trust her unconditionally. But he was a businessman, so he was not that dumb.
