I recommend "Quit Deadly Lover (Complete Version)". The female protagonist of this modern romance novel is smart and wise. She's not a weak female protagonist, nor is she a female protagonist who still loves the male protagonist in the end. In the story, the male protagonist was a typical black-bellied man. He was scheming and full of predatory nature. He had a crazy ambition for the female protagonist to pursue power. There were many heart-wrenching scenes, but the female protagonist did not choose to continue to love the male protagonist. Instead, she found her own career and growth. I hope you like this fairy's recommendation. Muah ~π
Well, in such a fanfiction, there could be various hints. Maybe Zoro's behavior might be more in line with typical female characteristics described in that specific fictional world, like being more empathetic or having different social interactions compared to the original male - character version. But it really depends on how the author has crafted the story.
One reason could be the sacrifices he has to make for the village. Naruto is so dedicated to protecting Konoha that he might feel he doesn't have time for love. His responsibilities as Hokage are immense, and he has to constantly be on guard against threats. Another reason could be past traumas. He has lost many people he cared about, like Jiraiya. This could make him afraid of getting close to someone again and losing them, so he gives up on love.
Zoro.to might have manga, but it's often associated with copyright infringement and potential security risks. It's better to use legitimate platforms for reading manga.
One reason could be the constant setbacks he faces. He might feel that no matter how hard he tries, he can't achieve his goal. For example, if he fails too many times in battles against strong opponents, he could lose hope. Another reason might be the loss of important people in his life. If someone like Iruka or Kakashi, who have been his pillars of support, were to die, it could shatter his dreams as they are so closely tied to his will to succeed for their sake.
