The protagonist doesn’t actually struggle at all because he’s the only reincarnated person to ever pick the Limit Break skill and is also strong enough to defeat a whole cave of giant worms right from the start. Really?
The attractive female lead is practically begging the protagonist to party up and offering to teach him about the world that he knows nothing about, but he repeatedly runs away from her and refuses… umm because why exactly? Still no idea–there was literally no valid reason.
The female lead doesn’t return from a quest and he waits three whole days before searching. Of course, he finds her engaged in a monster battle and moments from death (again) despite having waited so long. Are we supposed to believe she’s been fighting without food and sleep for that long?
