A protagonist reborn in another world.

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!?”
