Qi Yan, who came from the present world, traveled to a book with two male protagonists called "Gongjiu", and he was one of the protagonists. When he came here, he didn't seem to feel strange around him, but instead felt an inexplicable sense of belonging to the body with the same name as him. However, the other protagonist seems to be aware of his arrival and is always caring about Qi Yan, which seems different from the original text. The system in Qi Yan's body tells him that surviving is his main task. Maybe this task can be completed quickly, or maybe it backfires.
Intention: You and I are the watchers of two worlds after all
