The story begins similarlly—a mid-level corporate worker dies and awakens in another world as a 19-year-old—but from there, Eren follows a very different path.Erik, a mid-level office worker, had a simple dream:“Graduate college.Get a job.Screw MILFs.”But reality wasn't so kind to him. Due to his hastiness, he forgot to check the company's background and accidentally enlisted himself into a black company—a corporate hellhole that literally made employees work to death.Such was the fate of our protagonist, Erik.Exhausted after working nonstop 12-hour shifts for seven days straight, he lost his grip on reality and met a meaningless death, collapsing onto his desk in an office nobody would mourn.Yet, reality wasn't entirely cruel either.He suddenly transmigrated into the body of an 18-year-old—young, energetic, muscular, and brimming with vitality. And best of all?He woke up sleeping right next to someone!“What? I'm transmigrated sleeping right next to my step-aunt?!”Even crazier: in this new world, beauty standards were completely reversed. Here, the pinnacle of femininity was a skinny figure with small boobs and an even smaller ass, and women who didn’t fit that mold—busty, curvy MILFs—were mostly ignored, discarded, and lonely.“How crazy is that?” Eren voiced, grinning from ear to ear.But all of that was about to change, since he was here now. He'd make all MILFs his—starting with his deliciously thick, step-aunt.

The world is about to be destroyed to make way for an interstellar transmission array formation. A young man journeys through the stars to save his home. A bloody fantasy adventure.
