After her parents died in a car accident, eighteen-year-old Su Wan brought an old iron box left behind by her father and went to Qinghu Town to stay with her aunt, Su Yuqin, whom she had never met.
Qinghu Town seemed peaceful on the surface, but undercurrents churned beneath. Across from her aunt's home lived composer Shen Mo and his wife, Zhou Ning. Next door lived real estate developer He Ming and his beautiful wife, Lin Wei. He Ming set up a "□□ game," tricking Shen Mo and Lin Wei into sleeping together. The next day, Lin Wei was found dead in bed, and all the evidence pointed to Shen Mo.
