Hazekaya was just an ordinary guy… until he woke up in another world. Sounds exciting, right? WRONG!Before he could even process his isekai moment, he found himself being chased by a horde of horny male orcs.From dodging unwanted “affections”, to getting thrown in jail, to accidentally sleeping in horse crap and earning just enough to not starve. Between dealing with an ex-adventurer boss, getting tricked by his so-called “friends,” and realizing even slimes are harder to kill than he thought, his life in this new world is anything but the overpowered adventure he dreamed of. Instead of becoming a hero, he’s stuck as a low-wage wall repairman, constantly broke, and now the locals call him “Shitman.”With zero cheat skills, no legendary weapons, and a severe lack of dignity, Hazekaya is left wondering—“Why is my isekai life like this!?”

The world has changed into something like a game.

It resembles a survival virtual reality game where people were attacked by zombies and monsters.

And I was the last user of that game.

Why build a harem……when you can steal everyone else’s?Rejected without confessing. Friendzoned before even speaking.Too bad for them—he’s done being average.Armed with a system that thrives on charisma (even if his starts at rock bottom), sharp tongue, and unmatched game sense, Eiden isn’t here to play nice. He’s not the hero, not the villain—he’s the damn glitch in the story.The protagonist ?? He’ll outwit them.The arrogant beauties? He’ll make them kneel.The childhood sweethearts, the princesses, the cold beauties?They’ll come to him. Willingly.This isn’t your story. It’s his conquest.And no harem is safe.
