Review Detail of mishafond in Birth of the Demonic Sword

I like the story, the plots not really unique but its entertaining to read. My one issue with this novel is, well, the romance aspect of it. I don't care if the MC is deranged or a lunatic, however it doesn't make any sense why its in the plot. Where exactly does MC even find time for a romance is the grand scheme of things?!?!? It's so unrealistic and contradictory to how you established character... how exactly does romance fit into a novel where the protag is motivated by ambition to overcome the laws of the world in the novel? He wants powers, he actively strives for it and disregards the life of others like insects to achieve what he wants.... and now your trying to make me believe he can suddenly love after all that he's done and willing to do? It's ridiculous. You don't establish the essence of your character as ruthless and power hungry, devoid of feeling and morality, only seeking power, to add in a romance in the middle of the novel.... You might ask why you shouldn't do this? Easy! Because someone willing to do anything for power would NEVER LOVE ANYONE that would become a HUGE weakness. It contradicts your plot and established MC's sense of self/motivations/goals that the author wrote HIMSELF. You could see from the earlier chapters of this novel that the author kept trying to find ways to make a romance happen, inserting the obvious FL every chance he got and it only got worse, especially at around chapter(s) 592+ onwards. It would have been all great except how the MC progressed many many chapters earlier. We know that he's a psychopath, and he lacks any feelings. By the time the romance (AKA lovesick desperate author wants some MEOWWW) comes in, its not only unbelievable, it's an insult to readers intelligence and time spent reading.
