[Murder or suicide? Rich lady x downcast orphan, pure love or sadomasochism
Liu Xiaobing, an orphan who dropped out of college in his sophomore year and was sentenced to eight years in prison, killed his girlfriend's father, Bai Qiutian, the chairman of Tai'an Gene Group in Baiyuan City.
Eight years later, Bai Shuangshuang was married and had a daughter, Ding Wan'er.
The Wu Yue Wu Brigade of the Baiyuan City Public Security Bureau received an anonymous letter reporting that the evidence pointed directly at Liu Xiaobing's intentional homicide. So just after Liu Xiaobing was released from prison, Wu Yue went to Beijing to re-arrest Liu Xiaobing, who had not been heard from again.
Who sent the anonymous letter? Why did Liu Xiaobing run away? Why is Bai Shuangshuang indifferent? What conspiracy is hidden behind this?
