The shy and workaholic captain Shou (Lin Jiang) x the rich three-year-old forensic doctor Gong (Si Yan) Gong is not really three years old, he is older, Gong is three years older than Shou. I suffered a lot of psychological pain as a teenager, so my relationship with my family was lukewarm. Gong comes from a military family, but he became a forensic doctor, but his parents were very supportive. The writing style is long-winded and contains a lot of nonsense analysis, so don't spray it. The real-life sources of inspiration for some cases will be noted. If there are any contradictions in what I know from reading the basic theoretical knowledge, I hope you can point it out.
