@Prajith Truthfully i actually hope there ISN'T a female lead because this guy can't read a girls feelings to save his life and this also isn't the type of story that needs romance in it, its after all an action driven type of story....but that's just my opinion about it
@Yuki well just action all the time gets boring, romance sometimes(not always) adds a spice to the story and makes it more interesting. Imagine a near mute mc just going around killing monsters and clearing dungeons alone, seems pretty boring. Though sometimes romance ruins the plot and I've dropped quite a few series bcz of it. Btw everything I've written is just my opinion
Also I think without the girl mc would still be same level, since author is being pretty vague bout levelling, he can decide how much experience mc needs to level up
