"But then, my sister-in-law suddenly killed a servant by mistake and was sent to prison. After three years, when she came out, she was like a changed person, suddenly becoming so proud and awesome. She used to always get bullied by my second sister-in-law, but after getting out, the second sister-in-law was no match for her. I always felt that the second sister-in-law being driven out of our family and eventually choosing suicide had something to do with my sister-in-law. Of course, I don't think my sister-in-law did anything wrong. After all, it was the second sister-in-law who was causing trouble. I still believe that my sister-in-law is a person who keeps herself to herself and has been good to our Gu Family. It's just that my dad didn't have enough trust in her."
"Why didn't he trust her?" Gui Yuan seemed to ask casually.
