Lin Mo, a young reporter at Qiushi Newspaper, re-encountered his childhood neighbor's brother Bai Zhou (real name: Xia Ziwen), who is now a consultant to the B City Police Department, because of a "hanging case". With the appearance of playing cards with "⊙" patterns on them, the deaths of Lin Mo and Xia Ziwen's parents ten years ago were mentioned again. Who are Lin Mo's parents? Who are Xia Ziwen's parents?

But whenever they get closer to the truth, their feelings are tested like never before. In the end, does rationality defeat sensibility, or sensibility defeats reason?
Purpose: Pursue the truth and declare justice
