College graduate Wei Ran, also given as Yueran, is led by a cat into Dongji State, a fantasy world he never knew existed. While searching for a way home, he learns that the only train back to the human world comes just once every six months. With no other option, he takes up temporary lodging at the Weird Idea Shop, run by a cat named Yaya. Just as things start to settle, he finds that dragon scales turn up wherever he goes, and each time one appears it sets off a completely different strange effect. The result is a short comedic fantasy about a human's odd impact on a magical world.
