Main clues: The beginning of the movie is a timeline N, and there is a tragedy (omitted in the middle, but there is a dialogue that marks the theme of the movie: the dialogue between the male protagonist D and the villain after the arrest should still be paid attention to), D looks for various clues to solve the case , and a lot of unreasonable places related to him appeared in the process of solving the case, so after solving the case, he decided to travel back to four days ago (the interval was omitted), and after saving the heroine C, he returned to all the unreasonable places. Initially, it was C's home, and then when D found that the room layout was the same as he remembered after treating the wound, he suddenly realized that he might have rescued the heroine before the N-M timeline. But he failed to change the past (so the timeline of his last failure is also the timeline N at the beginning of the movie), which means that it is not safe to let C stay at home, and the result will still be killed, so he decides to bring C Go to C (omit another paragraph....), and then in the end C still didn't listen to him, followed the ferry, and then assisted the male protagonist to kill the villain (here I think it may be that the male protagonist did not bring along in the previous timeline The heroine failed because she didn't have the same luck + planning as this time to kill the villain), but in the end the hero of timeline N still hung up, and then the heroine met the hero of timeline N+1, and the heroine tried it out D, with what D said on the N timeline, I understood everything. (D on the N line is unbearable, after all, the screenwriter of the dog wants to force a great consummation.) The heroine was successfully rescued, and the tragedy was prevented from happening. At that critical time point on the N+1 timeline, Then separate a new parallel world. So it's easy to understand: after the villain was arrested, talk to the male protagonist in the tone of a Shinto victor, because he has seen male protagonists from other timelines and killed them, so according to his words Said he was victorious... (I can't imagine that you will still be killed by the dog screenwriter's plot in the end (dog head) In theory (?), similar parallel time and space are infinite and exist at the same time (very philosophical....) , so this type of sci-fi movie always has bugs big and small...
In fact, I have never understood that infinite parallel space-time is based on different choices.... It is difficult to explain why there are different choices....
