On the day of the crime, Qu Tong wrote a suicide note on the table, sent a package, and then put makeup on himself, and the water was mixed with sodium cyanide. Looking at the ring in her hand, Qu Tong cried, which was given to her by Su Muxin in high school, and the initials of the name of Qu Tong were engraved. Su Muxin received a text message from Qu Tong, which said that there was a power outage at home at ten o'clock, so that he could go back to accompany her. Because it was a wedding anniversary, Qu Tong made a big table dish, and Su Muxin brought a good bottle of wine back.
