Modern urbanites are calm on the surface, but secretly there is a yin and yang intertwined, and supernatural events emerge one after another. A group of five people who call themselves the "Spiritual Talk Agency" was appointed when they were in danger. Relying on their unique humor and courage, they solved a series of supernatural mysteries that seemed scary but actually hid human feelings and the truth. They travel between the world and the underworld as 'spiritual mediators' and with a relaxed attitude that has no taboos. Each case is full of challenges and laughter, and the humans and non-humans around him are gradually involved in the conspiracy. The order of the spiritual world is on the verge of collapse, and the protagonists have to face their own inner demons and dusty past. In the end, they completed their growth in a happy reunion, saving two worlds at the same time, and the firm also moved towards new life.
