Dane does appear insufferable on this manhwa. Idk about the novel. Haven't read it yet. But Dane probably grew up without anyone to teach him better. His circumstances toughened and molded him to who he is today. Can't blame the guy if he's clueless as heck. If we can spare understanding for Grayson, shouldn't we do the same for Dane (especially ppl like me who haven't read the novel yet)?
