You Say Only I Regressed? 15

Joo Lee Hwan regressed just moments before dying in the monster wave. He’d planned to prevent the apocalypse alongside his S-rank friend Taesung, who regressed with him—but the guy’s memories were completely wiped clean. “I have to stop the monster wave that’s coming in 7 years… with no money, no connections…?” After regressing, Lee Hwan is a fresh-faced office worker with no savings to his name. And his once-kindhearted friend? He’s lost his memories and turned so unbearably nasty that he might as well be a completely different person from before the regression… “Friend? I don’t remember having a friend like you. Aren’t you just some malicious stalker?” “I need useful people. If you can prove your worth, we might have a mutually beneficial relationship.” In the end, Joo Lee Hwan finds himself stuck working alongside the very person who will cause the apocalypse—all to save both the world and his own life. What the hell went wrong with Kang Taesung seven years ago? When yesterday’s best friend becomes today’s villain who constantly throws obstacles in your path, what do you do—kill the bastard or save him?
