### Summary
Following a powerful and chilling introduction where the 170km asteroid Rama destroyed Earth, protagonist Cheolsu has been sent back in time to prevent the catastrophe. Having faced the apocalypse with a single, resonant "Cheers," the ordinary office worker now appears to be navigating his school days once more. Readers are highly engaged by this "fresh" and "interesting" sci-fi premise, praising Cheolsu as a smart MC with a uniquely refreshing thought process for a regressor. The central conflict driving reader curiosity is how a non-scientist can possibly avert a disaster that defeated the world's combined military and scientific might. Speculation is high, with many theorizing he will use his future knowledge to become a top student and scientist. However, others question this path, suggesting he could instead invest in future companies to fund a private space program. Small details noted by readers, such as a recurring photo and the significance of book barcodes, hint that Cheolsu is already on the hunt for clues to solve this impossible puzzle, leaving the audience with a strong sense of potential and anticipation.
