Psychologist Shen Qingci, another identity is a judge who walks in yin and yang, specializing in treating "heart diseases" caused by human nature. In order to investigate a series of strange suicide cases, he sneaked into a mental hospital where elites gathered. Here, mania is not a disease, but is parasitized by "anger"; depression is not an emotion, but is eaten by "nothingness". And his ex-lover who became "crazy" because of him has the rarest monster living in his body - a "mirage" that feeds on human obsession and love. When the hospital walls began to seep with rules written in words, Shen Qingci understood that his patients were never sick, they were just sacrifices. This time, his judge's pen not only wants to cut off the yin and yang, but also split the disguise, and rescue the lover who he personally sentenced to the abyss from the hands of the monster.
