Heavy Spoilers
ok so we are going to explain that part too lol, the story is based on the "sisyphus" story and more specifically reminiscent of a paper that albert camus wrote called " the myth of sisyphus", which suggests that one must imagine sisyphus happy, and the only way that sisyphus can overcome the loop is to actually find some sort of meaning in the loop and do it willingly, does that help?
it's all metaphorical!
