This work tells the story of Su Qingji, a cold female psychiatrist who is cold on the outside and hot on the inside, who is the best in the industry. She meets Fu Yanci, a sinister boss who pretends to be a "yandere" patient and comes to challenge her. Starting from the psychological attack and defense battle in the clinic, the two began an extreme pull of intelligence, scheming and emotion. Fu Yanci originally wanted to conquer this iceberg, but in the step-by-step "strategy", he got a glimpse of Su Qingji's deeply buried childhood trauma, and his game mentality gradually changed to sincere protection. When Su Qingji's old enemy, a criminal who was proficient in mind control, surfaced, Fu Yanci resolutely tore off all disguises and used all his strength to fight side by side with Su Qingji. The highlight of the plot lies in the extreme tension between the two of them testing each other and fighting each other, to the deep emotional transformation of jointly fighting against powerful external enemies and achieving two-way redemption. It is full of excitement and the ultimate emotion.
