Ramblings from a Mental Hospital

(Behind-the-scenes flow + dark text + villain flow + s/elements) It begins with a patient being treated in a psychiatric hospital. He kept sharing funny stories that came to his mind, and people naively thought they were just his crazy ramblings. The stories he told kept appearing in reality, and all of them were just the fantasies of the mentally ill. Or could he predict this in advance. Everything seems to be controlled by an invisible hand. And what kind of picture will the puzzle piece in Su Bai's hand look like in the end?
