The neon lights of the city cover up the dimensional rifts, and the lives of ordinary college students are completely rewritten by an ancient bookmark found by accident. The moment his fingertips touched, the whisper of star trails sounded in his ears, invisible creatures from other dimensions began to appear on the street corner, and the palm of his hand could actually weave a shimmer that connected the two worlds.
A mysterious messenger visits late at night, bringing with him a contract legend that spans thousands of years; behind the urban ghost stories, lies the survival code of a group of people from another dimension. He must not only juggle between the classroom and dimensional adventures, protect the peace of those around him, but also uncover the connection between bookmarks and stardom. When reality and fantasy collide, when protection and exploration intertwine, those encounters, bonds and persistence between neon lights and star trails will eventually pave the way for a romantic and passionate legend of another dimension in the world. And this adventure spanning two worlds has just begun.
