In Tianlan City, a wave of "perfect crimes" swept across the city. The criminals left no physical evidence, the police were helpless, and social trust was on the verge of collapse. College student Bai Yi narrowly escaped death in a campus fire, but unexpectedly awakened the power of his eyes - the "Eye of Memory Recall". These eyes can penetrate the strong emotions deep in the human heart, trace the "emotional fingerprints" on objects, and even identify lies. However, every use was accompanied by intense mental exertion and physical discomfort, making him miserable. When a series of school disappearances shocked the city, Bai Yi discovered that the "perfect" suspect targeted by the police had cold "contempt and pride" hidden under his disguise. He realized that only these eyes could penetrate the fog and reveal the truth. He transformed into an "emotional detective", wandering on the edge of the rules, using unrecognized "emotional evidence" to secretly cooperate with official police officer Liang Jing. From the ultimate "despair" glimpsed in the victim's belongings to the afterimage of the murderer "laughing wildly and defying everything" at the crime scene, Bai Yi relied on his extraordinary ability to tear apart the disguise of the "perfect crime" step by step, revealing the main culprit behind it, and for the first time he came into contact with Professor Chen, the psychology professor behind it, and the larger and more secretive "emotional manipulation organization". The dual mental and physical tests brought about by his abilities, official doubts and potential contacts, and counterattacks from the masterminds behind the scenes all made Bai Yi's detective journey shocking every step of the way. How will he use emotions as clues to trace the source of evil and rebuild the collapsed justice in the foggy city? And what kind of high-level abilities and side effects will his awakened "Eye of Memory Recall" bring?
