For special reasons, Jin has to take the blame and fake his death in various timelines, in order to stir up the "protagonist's" emotions and achieve a certain goal.
But after going through a few simple worlds, he suddenly discovers that all the "protagonists" have become people he knows. What's more, there is more than one in each world... He clings to his burden with all his might, but every time someone slams it down on the ground.
Jin, dutifully completing his missions and wanting to cry: Could you all please stop flipping over my cover already!
