Forensic doctor Lu Zhixian, who returned from overseas, bumped into his predecessor who had left without saying goodbye eight years ago - criminal investigation captain Shen Yanchu - on the first day of reporting.
One conducts autopsy calmly, while the other acts vigorously and resolutely; they are obviously familiar with all the habits of each other, but they all say in unison: "They are just schoolmates."
Until a corpse with a mysterious identity tied the two people back into the same chain of evidence. Old metal buckles, blank consent forms, modified files and incomplete serial numbers gradually revealed the secret of Shen Yanchu's sudden breakup.
Everyone in the team thought Captain Shen was the best at judging people, but later they discovered that the biggest problem he faced every day was how to coax his ex back.
Lu Zhixian pushed up his glasses: "Captain Shen, you have to provide evidence when pursuing someone."
Shen Yanchu: "The evidence is conclusive, I still love you."
