In the corner of the bustling city, in a beverage shop called "Wangyou Ming", the sunny and cheerful proprietress Su Rui seems to be hiding an unknown secret. Not only can she see floating little ghosts, but she also has the power to deal with supernatural "obsession" and silently guard the tranquility of the city.
However, a series of bizarre jumping cases broke the calm. On a full-moon night, without warning, and with an eerily perfect scene—these cases attracted the attention of Lin Fan, the cold and rational criminal psychology consultant of the city bureau. All logical reasoning leads to an absurd conclusion: this is no ordinary crime.
When psychological consultant Lin Fan meets Su Rui, who is hiding his identity, doubts and temptations spread between the two. At the same time, opponents in the darkness are taking action. An organization called "Higanfang" is using evil spells to extract human "obsession" and cultivate dangerous seeds.
Under the full moon, the obsession field enveloped the streets, and nightmares descended.
What they will face is not only strange supernatural forces, but also the distorted and amplified desires and fears deep in human nature. A cup of specially prepared tea, a salvation or a trap? Can the collision of reason and spirituality illuminate the darkness hidden behind obsession?
Concept: The collision of human nature and obsession, rationality and supernatural, responsibility and growth, and the coexistence of light and shadow.
