The Law of Immutability

Woo-Ri Nam has always been the golden boy—wealthy, carefree, and blessed with luck that nothing can touch. But on the leap day of 2028, the date of his seventh real birthday, everything changes. What begins as a seemingly harmless reunion with an old classmate, Su-Bin Shin, ends in a brutal murder. Then, inexplicably, Woo-Ri opens his eyes to find himself back in high school, seated right beside Su-Bin—who has no idea that he has just killed his own deskmate. Trapped in a deadly time loop where nearly every timeline ends with his death at Su-Bin's hands, Woo-Ri grows desperate to escape his fate. After a series of resets, he finally arrives at one conclusion: the only path to survival may lie in making sure Su-Bin is happy. With just one life left, Woo-Ri sets out to give Su-Bin the happiest life he possibly can.
