Serious version: Make a dish, there are main ingredients and condiments, and be a time traveler, naturally there will also be a protagonist and supporting role passerby. As an ordinary person, he cannot be a protagonist or a supporting character, but if he can be a passerby, it is not a time-traveling experience in vain.
Easy version: If you don't have the protagonist's fate, why do you still want to have the protagonist's luck? If you don't have the protagonist's luck, why should you imitate the protagonist and commit suicide? Sure enough, you will die just by doing it! The reality only represents the heartfelt advice of the time-traveling god: just go to bed.
