Revenge On My Vicious Sister-In-Law

My cousin's wife wanted to set up her younger brother, who just got out of prison, with my sister.

My parents refused her, but she still brought the man to my house.

Later, my sister couldn't bear to be harassed and tried to commit suicide.

My relatives and neighbors also accused my parents and made them dare not go out.

After I came back from the mental hospital, I used my dad's phone and sent a message in our family group chat.

"We'll have a family dinner tonight to settle the marriage between them. Everyone remember to come."
